If you do not obey these rules, you will be punished (deranked forum account, deleted forum account, banned from clanchat, etc.).

1) All Jagex Ltd. rules apply (link: http://www.runescape.com/kbase/view.ws?guid=rules_of_conduct)
2) Show respect to others
3) No bullying, racism, or other types of violence
4) No abusive or pornographic content
5) No thread hi-jacking (example: stealing another player's customers in marketplace topics)
6) No useless n00b-calling
7) No spamming (double-posting is spam too!)

Most important rule: HAVE FUN!
