About the email sending: sorry for the problem. I tried to register an account, and i didn't receive the email either!
In the while i activated your account, so you don't need to get the email anymore.
Anyway, that is very strange, because i had a look, and while we were not able to get any email, other people got it and registered successfully.
Some does, some doesn't. I'll investigate deeper. Thank you for reporting anyway.
