This idea came up in the Phoenix forums on the Titan discussions, and I'm sure someone else has suggested it before. So excuse me, if this is an old idea.
Quite simply, it's almost the same as being in the clan so we can use:-
1. Clan money
2. Clan ranks and tags
3. Clan chat
4. Clan apartment
What we don't want is (Obviously)
1. Outposts
Discuss.
