Nostalrius Begins - Quality wow vanilla realm (1.12)

I tried to create a new account yesterday and I did not receive any activation email and of course the login id pass can't not be used. I have wait until now but nothing happened, already checked in spam but nothing.
P/s: I used yahoo mail, is this a problem?

Nostalrius as a project has been shut down years ago, so there is no point in registering.
