Re: One, OK, hundred, I have my doubts
If it was any time in the last 20 years, you can add "failure to read computing services advice sheet" to her list of sins.
Any university I worked at:
a) HIGHLY HIGHLY HIGHLY recommended that students use the backed-up network drive provisioned explicitly for the purpose of saving their highly-important assignments even if you saved it to floppy for working on at home. In fact, the first uni I worked at in 98 recommended that students save it to their home drive and email it to themselves at "Hotmail" or Yahoo or whatever.
b) provided a 1-page guide that was handed or sent to each student when their account was registered that provided such gems of advice. Directly after the information on their account name, email address, etc, so maybe that was the problem.
