This is pretty easy. Do not upload anything that you wouldn't show on a big screen to your mother and her bible study. If you do, I'll remove you. If you're mad at your mom and decide that you would in fact show that to her, I'll remove you. Do not violate someone's copyright or I'll remove you. This is not an auction site, a classifieds site, a place to promote your business, a place for your personal rants, or a porn site, and if you try to make it one, I'll remove you. Okay, okay, for some of you this is fly porn and, well, we will worry about you but you can register anyway. Just... you know, Don't be a Moron. (Here is the legal version.)
