Indeed, and since the bully's actions would be restricted to either leaving things alone or completely destroying the deck the impact would both be quickly obvious (resulting in a restored backup, hopefully) and there would be no excuse of "oh I was just having a bit of fun", so there would be nothing to gain by doing it. > I think this could be of value in some situations, and I think it was > a reasonable enough feature request. Agreed, I didn't mean to shoot it down before, just hadn't thought about it in these terms and felt that the OP might have been asking for something impossible (full protection of the file). It's certainly worth adding as an optional feature for exactly this kind of classroom situation. > Cheers, > > Craig. > > -- > > You received this message because you are subscribed to the Google Groups > "mnemosyne-proj-users" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > For more options, visit this group at > http://groups.google.com/group/mnemosyne-proj-users?hl=. > > > -- You received this message because you are subscribed to the Google Groups "mnemosyne-proj-users" group.
