Here's my stance. Posting to the "best of one's ability" is a realistic expectation of the more mature forumers. Everyone else, so long as they're making an honest attempt at intelligible discussion, ok. That's a big difference from making yourself a problem. The people that continually and blatantly make themselves a problem for myself, the rest of the staff, and other forum users is what I'm looking out for.

One thing I will be suggesting is the ability to revoke a member's ability to access this sub forum.
