This is the first check-in of support for groups.
It's very early (it doesn't actually do anything yet!) but you can define groups and get an idea of how the interface is shaping up. I also wanted to show that I have actually done something on this! :-) From here my plan is to add group support to the modules, one by one (forums first), then go back and clean up some of the central interfaces, graphics etc. Finally, test, test, test and get 1.2 out well before the end of February.
