Hello and welcome. All the rules are in the server rules post, although some of them are a little obscure, reading sanction threads helped me a great deal.
If you need help or have any questions you can always post on the forums. Additionally you can stop by the disco help channel where you can also meet some a good group of friendly players (link in sig). This is in skype which is the chat program of choice of this community, I highly recommend getting it if you plan on being active here. Also I have heard the link may not be compatible with some newer versions of skype, if this is the case just PM me your skype name if you want to check it out.
