For the sake of civility the rules are pretty straight forward:
1) No Racism (Nothing offensively or overtly racist)
2) No intolerance toward sex, gender, sexual orientation.
3) Do not harass anyone. Teasing is different, and we all know the difference.
4) Use your brain (common sense) if you constantly have to ask me or a mod if its okay to say something... you're doing it wrong... not only are you wasting our time but you're detracting from the fun we're trying to have. In other words, I'm not YOUR baby sitter.
If you break any of these rules you might be warned but you will immediately or eventually be banned.
