Not really 'rules' per-say but they are guidelines of how to use this.
As a member of r27 Gaming, I expect that you all have made some sort of game at one point in you life. Well, good. All you have to do is request a forum in your name in the "Welcome" category and you will be able to write topics for each individual game and have complete control over that discussion
No posting topics in other peoples forum.
If you have a company, please feel free to post in there. If it is a company, only company members should be posting topics.
