lol, http://www.hipforums.com/forumguidelines.htm if you aren't sure and just make sure you take everything here with a grain of salt and you'll do fine.
Hey - don't sweat it man. Hip Forums is for fun - Not to stress you out. Don't put any nude pics, be relatively civil, don't try to stir up trouble and you'll be fine. You can talk about ANYTHING you want to - and nobody will know who you are. Go for it man. Have fun.
