You make great extensions (I'm a long time fan of ReDJ).

My users create pet profiles using a CCK. I use Form2content, which saves information as native Joomla articles. Sometimes I have clients (like rescue centers) that have multiple staff members that may need to edit the same animal profile (i.e., the same Joomla article), so they need to be assigned to the same custom group.

Can you think of a way to use Auto Groups to allow specific users (like the owner of an animal clinic) to add their Connections to a group, then to allow that group to edit specific articles? The Auto Groups plugin is based on fields in a user's profile. My challenge is that we can't let everyone choose their groups simply by selecting a field in their profile. Otherwise it would be easy to add yourself to any group and edit any animal profile.

If possible, I prefer to keep management of groups with the clinics because their staff changes constantly. Do you have any ideas?

Thank you for the advice. I started testing and I think you are correct; a simple frontend interface should do the trick. I'll allow the administrator of the clinic to access a form that will load their established connections from Community Builder. Then they can designate members in their list to be moderators of those articles. Any time they uncheck a member, they will be removed from that group.
