Instead of entering userids, I would like to enter Social Group IDs or UserGroups IDs so that only and all of the members of the group can participate.

I have this working on my dev system, allowing a list of users to be entered and an optional user group. Just one user group though, multiple users group was proving a problem to present to the user as there is no nice user group lookup like there is for user names, multi-select drop downs don't seem to work properly from within vB, and I thought it a bit naff to expect users to know user groups by ID. Will this single user group be good enough? If so I'll release an update with it in.

I haven't look at the social groups. There could be a performance overhead with the social groups one as I suspect I'd need to query another table to find out what social group each user is in.
