is there a registry entry that can be edited so that

So you'd add this registry entry to their home PCs how?<g No, no such
entry in any case. I'm afraid that file properties are readily editable.
It's probably impossible to know for certain who first saved a file. If you
gave each student a file to start with, and each was subtlety different that
might be a trace. But that's a lot of trouble, not failsafe and doesn't
prevent students from 'sharing' the work that goes into completing the
spreadsheet if not the spreadsheets themselves.

| hi~

help
