1. No advertising
(unless it's in your sig.)

2. No flaming.

3. No links to inappropriate content(like porn)

4. Try to use proper grammar and spelling. If you misspell a word occassionally, it's okay though. If you do it so much that it seems intentional, you might be warned. (ie. "omg teh h4x0rz r c0m1Ng!" is bad)

5. Do not double post unless the posts are 24 hours apart.

I'll come up with more later. Since the board if fairly new I guess this is adequate for now.
