I don't know of any forums that specifically cater to cliques, really. I don't think many admins really want them. I just figure, they're unavoidable. You go to work, and people clump off into smaller subcommunities/cliques, it happens in school, it happens everywhere- it's just what people do naturally when they're in a community with too many people in it to care about individually. The forums I own are still small, so I speak more as a member of lots of big forums. I think most people tend to resent being labelled, anyway. Actually, I think the new social groups feature of the 3.7 beta series of vBulletin might be an answer to this. It'll let like-minded individuals cluster without you having to cater to them specifically.
