I wasn't able to sign up as the site just gave me "not available in your country yet". Not that I haven't seen stuff like this before but it's so annoying to get excluded on things. I'll just have to wait for the world wide public release then.
I think that they are going to send out letters if a person doesn't get accepted as well, so it may take some time. At least I thought that was one of the options. So good luck everyone!
