Only thing I've got at the moment (not sure if anyone else pointed it out) is there aren't any rules yet. Forum is still new, but I've got a few suggestions.
1. No double posting. I know a few forums where this is a serious, serious offense. I can agree with it, some people take the liberty of getting 50 posts in bumps
2. No leet-speak. I'm taking this from SomethingAwful, one of their rules is no leet-speak, but with them they include "lol". I think that's kind of stupid, some things are okay, like "lol" and some abbreviations, but at the same time when a post is nothing but spewed out internet memes you attract /b/tard.
3. Mephisto made a good one -- use the search option to see if someone else has posted what you're planning on posting, and keep threads on the same thing to a minimum.
