(You also get to answer profile questions like which HP book is your favorite and which HP movie and which HP ship, and... I'm still trying to figure that last one out, although I'm so vanilla that whatever I put will probably enrage people. LUPIN/TONKS OMG HOW COULD YOU?? This is not even to speak of Harry/Ginny.)
By the way, if you don't already have some kind of account at the Leaky Cauldron, and you don't mind Ravenclaw getting 20 points for it, direct-message me here with your name and email (I mean, I don't need your real name, just what you want me to put on the invitation) and I'll send you a referral. You can join without one and you can join whichever house you want whether I refer you or not. And I'll friend everyone back regardless.
ETA: Wait, I tell you what--I'll screen comments on this entry and you can leave your email here, and I'll unscreen any comment that doesn't have an email in it if you want to just comment normally.
