Hi Everyone, SLAC user computer accounts are to be disabled on Dec 31, 2009, unless the user has successfully completed the SLAC Computer Security Course CSC101. This course can be taken on the web at http://www2.slac.stanford.edu/computing/security/education/CS101/description.htm It requires either a SLAC unix account or SLAC windows account to identify you. You will need your account password to log in. You can either take the full course and complete a test at the end (takes about 25 minutes), or you can take the challenge quiz first. Passing grade is 80%. If the course is not successfully completed by Dec 31, all your SLAC computer accounts will be disabled by SCS. If you have any questions, let me know. Thanks much, --Ray
