Here's a practical tip from Ron Lambert at Sargent Park School to help you to remember to always logout when using our web-based mail software. When you login to our Division mail server, click on the "Personal Account Options ..." pull-down menu at the top of the screen and select the "Edit My Preferences" option. Find the menu item entitled "Menu buttons in read message screen:" and change the radio button from the default setting of "Bottom" to "Top". Click on the "Save" button in the bottom right corner to complete this change. Now the user will always be directed back to the top of the message to take further action. Being in close proximity to the "Logout" button, in the top right corner, should help remind users to use this procedure always upon ending an e-mail session. Is there any way you can still gain information from a

E-mail message - May 4, 1999
One of the Random Acts includes just writing a Thank-you note to someone who you really appreciate for doing a great job but rarely get a chance to tell. They could choose a friend, parent, coach, teacher, neighbour, sibling, stranger, etc. etc. Just someone that they appreciate. E-mail message - June 15, 1999

"Pay
It Forward" - A movie with a message
When Richard Burkett called me to discuss ideas that might be used to help his Grade 5 students better cope with the tragic events of September 11, I recommended that Richard might consider investigating a movie that my wife and I rented this summer called "Pay It Forward". This movie was directed by Mimi Leder and was based on the best-selling novel by the same name by Catherine Ryan Hyde. The movie "offers a noble premise which speaks of the need to improve the world, and which redefines the responsibilities of teachers, parents and children." On the first day of school, students in a middle years school in Las Vegas are challenged by their teacher to "think of an idea to change the world -- and put it into action.” Trevor McKinney, the Grade 7 star of this movie, designs a process in which a person who benefits from someone else's act of kindness or good will must "pay it forward" to three more people who, in turn must pay another good deed to three other people. Educators will definitely find this movie thought provoking.
"The Teachable Moment" - Web Supports for Educators
Ron Lambert of Sargent Park School willingly shared a variety of web sites that he felt educators could use, in light of the terrorist attacks, to help students and staff with their own personal understanding of the events and days following September 11. They are included below:
PBS America Responds
The New York Times
CBC
National Institute of Mental Health
[Editor: As I get older, I am beginning to appreciate more and more the sage advise that I learned many years ago as a Cub and Scout. Perhaps if we all adopted the Cub promise "to do a good turn for somebody every day" and the Scouting custom of "always leaving a campsite in better condition than when you found it", people and our environment would be better for it.]

As many of you know, I believe very strongly in what educators often refer to as "the teachable moment". It's that, sometimes rare, occasion when a variety of circumstances and conditions prevail to afford an opportunity to learn something that will have a profound impact on the individual. For me, a recent teachable moment involved having my computer laptop becoming infected on September17th. with a nasty computer virus known as "W32.Magistr.b@MM".
Immediately a number of questions undoubtedly spring to your mind?
Unfortunately I did not immediately realize that my laptop was infected. Although I was running McAfee's VirusScan, I was not fortunate enough to have the virus protection software immediately alert me that a virus was detected in one of the e-mail attachments sent to me. Furthermore, even though I know that the virus scanning process can slow down the computer's operation while it is scanning files, I had my virus software running. It was not temporarily disabled to allow me more speed. The question remains ... how do I know that my laptop was infected?
It was informed computer users who quickly used e-mail and the telephone to warn me that they had received a somewhat cryptic e-mail message from me containing an attachment that was infected. For example, here are two different infected e-mail messages that were sent from my laptop:
Subject: Use a Theme
Message: "Choose from more than 30 predesigned Themes that include varying graphical elements such as backgrounds, bullets, text formatting, and color options."
Attachment: pages.com (infected)Subject: Realize that if you cut a sound
Message: "When you click on a sound or add a sound, you can change its name and choose the sound file. You can also test the sound using buttons. When you are done click the button labeled Close."
Attachments: refer.com (infected) & Game_Maker.doc (not infected)
Another friend received an e-mail from me in which the Subject stated: "There are pens o f different". He didn't open the attached "multiple.bat" file (which was indeed infected) but emailed me immediately asking why I had sent such a cryptic message and also wondered why I hadn't attached a signature file, my name or my standard closing of "Take care & keep smiling (:-)". However those who really know me and my writing style are aware that it would be very difficult for me to write a succinct message containing three or fewer sentences (:-).
However, it was up-to-date virus protection software and supportive colleagues and friends who quickly e-mailed me back to indicate that software on their computers had trapped or quarantined infected attachments containing the "W32.Magistr.39921@mm" virus (which is just another alias for the "W32/Magistr.b@MM" virus).
So ... my laptop was indeed infected and the virus was forwarding attached files from my laptop (which the virus was infecting and propagating). However I began wondering how I contracted the virus and why hadn't McAfee's VirusScan warned me when I had originally acquired the virus infected file.
The first thing I did was visit McAfee's Virus Information Library at: http://vil.mcafee.com/default.asp I entered "Magistr" (without quotes) into the search field and learned that the strain that infected my laptop was created on September 3 and that a removal process was established on September 12, 2001.
The next task was to inspect the McAfee's VirusScan software on my laptop only to find that the last time that it had updated the virus protection DAT file (used to identify viruses) was in late August. Unfortunately, my virus scanning software was working but it was unable to detect this new virus because it was approximately one week out of date. However, thankfully my fast-acting friends and colleagues alerted me to the fact that my laptop was sending out cryptic e-mail-laden infected attachments. I quickly updated my DAT files, scanned my laptop, removed the infected files and then analyzed how the virus had tried to infect others using my laptop as the virus distributor.
I purposely moved from Outlook/Outlook Express to Eudora e-mail software last February in order to reduce the possibility of becoming infected with viruses that were written to attack Microsoft products. I even went as far as to remove all data from the Outlook Express address book. Even though I was not planning to ever use Outlook Express again, this precaution was taken because I knew that viruses had been known to send out infections to others using the infected microcomputer's e-mail address book.
Imagine my surprise when I received "bounced mail" back from four individuals who alerted me to either the cryptic e-mail message that I sent out or the fact that e-mail sent by me contained the "Magistr" virus. However, I was shocked when I did some investigation to learn that three of the four individual's e-mail addresses WERE NO LONGER IN MY ADDRESS BOOK. I had deleted their addresses, along with the entire Outlook Express address book, last February!.
I then searched my complete hard drive looking for the four e-mail addresses of colleagues who had notified me of receiving the virus only to find the e-mail addresses in the Outlook Express Outbox.dbx file. Although I had deleted all address book references, I had not deleted e-mail received in Outlook Express' "Inbox" or e-mail messages that I had send out and still remained in my "Sent Items" folder. It seems the virus attempted to spread itself by sending out fictitious e-mail from my laptop to ANY E-MAIL ADDRESSES THAT IT COULD FIND ON MY LAPTOP!
As you can imagine, this virus infection process can proliferate widely when a person shares e-mail with a wide circle of friends or colleagues. We all have received e-mail in which we are one of several recipients in the TO: field or there were other e-mail addresses in the CC: field. If, like me, you tend to leave these messages in your "Inbox" or keep the messages in your "Sent Items" or "Out Box", some viruses can search out any e-mail address stored anywhere on your computer (not just the Address Book) and share their destructive attachment with many of your friends or colleagues and even others with whom you have never directly communicated. These other individuals may also receive a virus because their e-mail address was listed as an additional recipient on an e-mail message that was sent to you and although their names don't appear in your address book, their e-mail address is on your computer as part of an in-coming e-mail message. It is this e-mail address which could be a potential target of an e-mail virus which is clever enough to search out any e-mail addresses on the infected computer's hard drive.
What can responsible Internet users do to avoid viruses?
1. As, illustrated in the previous material, it is not sufficient to have virus software installed, one must be diligent in keeping it updated on a regular basis. If you have Internet access, visit the home page of the developer of your virus protection software and ensure that you have the most recent version of the product and it's related virus signature files.
2. Check to ensure that your virus checking software is properly
configured to detect viruses. For
example, Internet users should visit the European Institute for Computer Anti-Virus
Research (EICAR)
Online web site at: http://www.eicar.org/anti_virus_test_file.htm
This web page allows visitors to download an anti-virus test file. There are
four possible download files that can be accessed which are all obviously
non-viral but which your anti-virus software, if set up properly, will
"detect" as though it were a virus. One may wish to copy the
"EICAR.COM" file to a floppy and double-click on the file name to
see if a message similar to the one shown on this page appears indicating
that your virus software is working. Obviously you should click on the
"Delete" button as indicated to remove this test virus as well as
any real viruses that may be identified with your anti-virus software.
3. Since most
viruses are acquired through e-mail attachments,
never open any e-mail attachments from e-mail addresses you do not recognize
or in messages that seem somewhat cryptic.
4. Disable any e-mail settings which automatically checks or sends e-mail. Set the e-mail software so that the individual has to click on a button manually to check for mail. This way, the individual can immediately taken precautions if a virus or a strange attachment is detected rather than have the potential virus begin infecting your computer and potentially sending out viruses from your computer undetected.
5. Be aware of "double dot" attachments. Kevin Druet, in Information Services, passed along this tip. As many of you know viruses tend to be transmitted through executable files. Such files end with file name suffixes like ".exe", ".bat" or ".com". However, if one was to right click (to see the properties) on an infected e-mail attachment file, one might be surprised to see traditional pictures files with names such as: "vintage car.jpg.exe", "B&B.gif.com" or ", "cartoon.bmp.bat". However if one attempted to open each attachment expecting to see a rare "Rolls Royce", a "Bed & Breakfast cottage" or a "political cartoon", no image would appear but rather a computer virus might be released into your computer. Unfortunately Windows/DOS looks at the "first" three characters following the dot which in these cases represent traditional picture format files. However virus creators have been know to infect picture files by tagging an additional "executable" file name after a second "dot separator". Should you ever encounter any attached files with two dots, immediately delete the files as they could have potentially damaging viruses imbedded within the file structure.
6. Do not automatically open e-mail into a viewing pane. Configure your e-mail software so that you have to open each individual piece of software in order to view its contents. Some of the newer viruses can spread through your computer if they are automatically loaded into a viewing pane.
What can our school division do to help reduce the spread of viruses?
1. The Division has negotiated a licensing arrangement to utilize McAfee's VirusScan anti-virus software to protect all Division computers. Furthermore, a process has been initiated to ensure that this software is updated on a regular basis.
2. With the recent Nimda virus attacks, Technology Education took a pro-active step to shut down our Divisional web server, even though it had not been infected. This web server contains more than 6.5 gigabytes of educational resources which receive in excess of 24 million "hits" per month. We felt that if one of our local school web masters inadvertently posted a Nimda-infected file to our server, this web computer could potentially infect many visitors. Shutting down this server and scanning it with the most up-to-date virus software preserved the integrity of this valuable resource.
3. Division employees whose e-mail address ends with "@wsd1.org" are fortunate in that steps have been taken in an attempt to strip off known viruses as they pass through our e-mail server. This software will automatically scan the attachments of all incoming and outgoing e-mail.
If an e-mail attachment contains a recognized virus, the attachment will be cleaned of the virus or deleted if the entire attachment is a virus. The sender of the e-mail message will automatically receive a notice from the "POSTMASTER" that the e-mail contained a virus similar to the following:You may wish to contact a technician to have the virus cleaned from a computer at school if you receive a similar notice to the one above. This new procedure of scanning e-mail attachments for viruses on our Divisional e-mail server does not mean you will not get a virus on your computer as there are several ways to infect a computer with a virus. This procedure simply provides an additional level of protection and will help to warn employees who may not know their school or home computer is infected. If this should happen to you, please act responsibly and arrange to have the entire system scanned and cleaned of all viruses before using the computer again."The WSD1 anti-virus software on wsd1.org has reported that you sent an E-mail to "johndough@wsd1.org" (and any other e-mail addresses found in the carbon copy field as well), containing the: virus name in the sample file attachment.
The subject of the E-mail was "Sample E-mail Subject".
The E-mail containing the virus has been quarantined to prevent further damage. Please notify your computer technician."

[Editor: Last year, the Elementary "Stand-Alone" Report card program was based on a run-time version of Microsoft Access. This year, Patrick Logan, with input from many educators, has created an enhanced Elementary Report Card program which still runs in a stand-alone format but incorporates a built-in text editor and spell-checker in the anecdotal component. This enhanced product now prints report cards in an 8½" x 11" format and is created using a run-time version of "FileMaker Pro". Educators, looking to recover valuable hard-drive space, may want to uninstall last year's version of the Elementary "Stand-Alone" Report card program from school and or home computers following the steps that Signy has identified below.]

The longer I live, the more I realize the impact of attitude on life. Attitude, to me, is more important than facts. It is more important than the past, than education, than money, than circumstances, than failures, than successes, than what other people think or say or do. It is more important than appearance, giftedness or skills. It will make or break a company ... a church ... a home. The remarkable thing is we have a choice every day regarding the attitude we will embrace for the day.
We cannot change our past ... we cannot change the fact that people will act in a certain way. We cannot change the inevitable. The only thing we can do is play on the one string we have, and that is our attitude ... I am convinced that life is 10% what happens to me and 90% how I react to it. And so it is with you ... we are in charge of our attitudes.
