Woohoo. I somehow managed to suppress my excitement, but now it's arrived I can't wait to get on it.
Can't log into my Backerkit though. The link in Playotonic's email is broken, and I can't log in to from the main homepage either. I requested a new password and apparently Backerkit doesn't have my email on record! *gulp*
Edit: Got it. I went through the BackerKit survey link and found my keys that way.
