Halo 3 doesn't support clans. The Halo 2 clan thing didn't really take off. However, XBL is supposed to introduce clan support in a future update.
Now with that said, Bungie's website has a group feature that allows you to created groups. It would be cool to have a TOJ or CGAlliance group there. The nice thing about groups rather than clans is that you are able to be a part of multiple groups while you could only be a member of 1 clan.
my bungie account is old enough that I can create it now if you'd like. From what I can tell, the only thing it would give us is a forum though, which we already have here.
