Templates currently aren't allowed. Only Dragonborn. I wish to change that, but I'm going to be careful about that. At least, unless it's been changed, and in that case, I fear the commoner.
A hidden sub-forum would be useful, yes. Not sure if it's necessary. Now, I think conversation will be key to accepting homebrews, especially systems and classes. Feats and spells not so much. One thing I do know is that it would be annoying to do that ArenaManager thing. The problem Tshern pointed out. Thing is, is not locking the thread going to be a problem? I mean, if not we can just have a separate stickied thread for ref talks about homebrews. Though that hidden sub-sub-forum does sound nice...
