There is also a handy how-to guide with videos of the signup process if you are unsure about the new signup form.
It might take awhile to get the signup page to load, because they're really getting hammered right now (it keeps timing out for me). I think I'm going to finish writing my letter and working out the details of my requests, and then come back to it a little later.
