The forums are here for anyone who wants to use them. In this case it means that if you want to post in them you have to be mature and polite. There will be no flame wars, trolling, racism or porn,... on it. Also making publicity for other websites is not allowed unless a person of the CCReviews team allows you to. Putting a link in your signature is also being looked at as publicity for the site of that link.
Not following these simple rules can result in a ban, though first a warning will be given.
