I guess I might as well spill the beans here. If you want to make a forum, just follow these steps;
1) Search the game and make sure there isn't a forum for it already.
2) If you can't find anything, go to the submit page located here;
http://www.supercheats.com/submit.php 3) Click the link at the bottom to ask a question for a game that doesn't exist on SC yet.
4) Enter the name of the forum, the platform, and ask a random question for the game.
Rich will approve the question, and the forum will be made.
