Okay, great. I forget that everyone doesn't know UNIX admin commands... chgrp of course is change group, chmod is change modes, and chown is change ownership. If you do an ls -l filename you can see the permissions etc, and you can add group write permissions if they aren't there already by typing chmod g+w bookdesc* for instance. I'm set for this month, and hope I can actually help take a little pressure off you.

How are you doing?
