Can this extension be used with CentralAuth?
I ask because CentralAuth has a system for global user groups, but I would prefer this method of creating them, since it says CentralAuth groups do not show up in Statistics or ListUsers.
This would require $wgSharedDBPrefix, so first you must decide on whether you can use CentralAuth or shared tables for uniting users. I don't really believe the two can be comfortably used together (I think CentralAuth chokes on a $wgDBPrefix).
