You can find the full rules here. But there are several that we wish to point out, just in case, because they're come up several times in the past week.
FLAMES, PERSONAL ATTACKS & DISRUPTIVE POSTING
Do not post deliberately inflammatory, argumentative or aggressive messages. If you disagree with a person, you can argue with his ideas in a respectful manner. Don't attack the person, his personality or what he is, even in an indirect way.
And:
If you were banned and want to join again, send an email to one of the moderators about it, otherwise the new account will be terminated as before.
In particular, the latter rule applies across both forums for the moment. If you can't contact moderators via the forum, you can reach me as @emk_langs on Twitter and I'll forward your message to the other moderators. Thank you.
