After you have registered you will get the message, failed to send email. Although this message is annoying, your register did complete. Your account needs to be setup and needs to be activated after you have registered.

At this moment i am the only one who knows how to do this, so after you have registered on the DKP poke me, and i will set up your account so you can sign up for raids!

Greetingz,
