Okay, more like guidelines, but close enough.
1) You can say whatever you want, pretty much.
2) If your name is Paul Corby, don't post.
3) Take another look at rule 2 just to make sure.
4) If you're pressing Submit on the third one-liner in a row, you might want to stop and think about the quality of what you're posting.
5) If you're having problems with flood control, see rule 4.
6) If your sigs are longer than your posts, see rule 4.
7) Be nice.
8) If you're having problems with rule 7, don't expect people to like you.
9) Don't quote anything you're not responding to. We've already read it once.
10) Colored text is pointless and annoying and screams "noob! restrain me!"
11) The photo option is for photos. That is why it is described as such. Use it appropriately, please.
