The Underground is for discussion of everything that is Bungie, not just Halo. Halo is a very small part of that. The Septagon isn't for "community discussion", it's actually for suggestions to improve Bungie.net and the Seventh Column. The Maw is the only forum specifically for one game. However, I don't think that a specific Halo Xbox forum is a good idea, since it would be hard to keep track of all the forums. It's hard enough with the five we have already, and I don't even pay attention to The Maw, since it's not relevant to me. - Reiginko
