Really, there's only one rule for this forum. That's not too bad, is it? :P
Religious and political discussion is acceptable, as long as it is approached in a decent manner. Mature, respectful debate is okay. Full-fledged bickering is not. If discussions start to get out of hand, members will be warned. If the problem persists, the discussion will be taken care of as I see fit, which may include deletion of the topic. Don't make me regret allowing religious and political topics.
Edit: Okay, there's one more rule in effect now --- no commercial topics! Spammers will be IP banned without warning.
