BuddyPress.org

@firetag I like the idea of Group Tags (plugin already available) AND Group Types (needed). I also like @pcwriter’s suggestion of having a drop-down with group types when members create groups. The groups types should be general, high-level categories. For example, if you look at BuddyPress.org’s Groups, you’ll see that some are labeled “Support Group,” “Plugin Group,” “User Created Group” — I like that (though I’d consider having some Group Type labels for the Admin to see and use only).
