Re: [seul-edu] youngsters logging in
at my school all of the student accounts have null passwords. the only
people who have passwords are the teachers
and the administrators. there isn't really any security troubles either.
no one cares to read anyone elses files cause
there isnt anything interesting there other than typed stories. unless
these grade ones have important files than
null passwords might be a good idea. i dont know your situation of the
school so maybe this wouldnt be a good idea.
but those cuecats do look cool.
ps - how would u make the access cards for the cuecats? are there any
bar code making software for Linux?
