I get where you're coming from, it doesn't really matter that there are X number of tribes, but I still think having a whole other tribe dedicated to moderation for an already existing tribe is excessive. Just from using forums for gaming clans/guilds I found that having private posts is sufficient.

There's the whole other idea of having "sub-tribes" which could then be made private. But I think we could be damaging some of the simplicity of Snapzu's type of platform.
