Welcome back, or welcome newbie, make yourselves comfortable. If you're not sure why you're here because you don't watch the show, go get started immediately. If you're not sure you should, go look at this primer and then get started immediately. Because season four is upon us!
(PSA: I can't actually watch the episodes until Tuesday morning (GMT) but I'll definitely be around after.)
Oh, and stealing from Tash, if you click the above, you'll get emails whenever there's a new comment on this post!
