Pundit, here is a suggestion, make a subforum call it "Forge Talk" or some such. i doubt it will slow posting on the rest of the board, and people wont feel they're being pushed around, or whatever it is that people feel when they percieve a topic ban.
Change your request from "don't talk about it," to "talk about it all you like but keep it in here" - kind of like an adult forum, but sans the porn and charm. That way, if a given thread starts to go "wrong" you can split it, remname it and move it over. Nothing lost, nobody pissed off and silenced. Furthermore, anyone who doesn't give a rats ass about theory (me for instance) can avoid the same.
