We're currently having some problems with the account registration and password recovery at the website. Currently our mailserver doesn't send activation or password e-mails.
If you can't wait until we fixed the problem, contact N|liQ at the IRC channel #nihilum.wow on Quakenet.
Creating multiple accounts won't help, so please just don't do it
We are taking care of this issue and I'm going to post something in here as soon as we solved it.
