The kind of discussion I think you mean, is what we have going on in the clans here at ZU. Check out the
Clan FAQ for more info on what the clans are all about, and how you are placed in a clan.
Basically, clans are a place for a lot more general chat than the main forums. They have community threads, scrapbook threads, gaming threads, and generally more fun and, dare I say, slightly more spammy threads. This all helps toward a closer knit community feeling.
