Dear Mike
1) Read the manual
2) Make the user a member of a group in server manager
3) Make the ibay ownership a group, and give it read=group, write-group permissions, again in server manager
4) Read the manual again, because it does have a lot of good stuff it it (both of them)
5) Read everything on the e-smith.org web site
6) Read lots of old posts on these forums, its all there.
Regards
Ray Mitchell
