Think you're asking for trouble Adam with the politics one. At the moment there's isn't too much political stuff here and the litttle there is is usually decent debate (now Conor74 is gone ) I think having its own section wouldn't encourage those who are really into politics (they're going to post it in OT anyway) but rather would encourage the idiots to post.
As for the TW forum, I think to make it viable you'd have to have it for registered members only and you can either have it heavily moderated or make it a "not safe for work" board. Not saying you should have hardore stuff either BTW
The only other forum we have on our board is the Gambling forum. People give hints, tips and picks on all sports. Just an idea
