Your basic no, no's apply.

No spamming.
No hate speak (unless it's part of the story line, and your character is just a cranky person).
No godmoding. Please, do I even need to ask.
No violating the individual rules of the roleplays put forth by their posters. If they come to me saying you broke a rule in their thread that was perfectly reasonable rule, I will be forced to take action against you.

All in all, I'm sure we won't have any problems.
Have fun, and be respectful to your fellow players!
