I would be in favor of a "members only" board or a moderated board (either instead of or in addition to what's here). I typically don't read either this or the Rag board because there's so much crap posted by folks who just want to be irritating.

You could certainly get a list of approved members by looking at who buys the TG on line. Also, it seems there's a relatively small population of posters.
