Why join hogwarts?
Well I don't really know it's really just that you want to and it gives you a place to hang out on the net, will hopefully give you access to special chat rooms and pics. and other harry potter obscure facts. gives ya stuff to do when you're bored, not to mention harry potter stuff is usually just cool all altogether. Not to mention (if this works for you) it can give you a way to escape for a bit of time out of this humm drumm world that we live in.
