New User Registration issues

We are having issues related to sending registration e-mails. This is resulting in the inability to create new accounts. My hosting provider is investigating. In the mean-time, if you have tried to register and not received a registration mail, send an e-mail to:
rc2012-at-pblue.org from your e-mail address with your user-id, and I will manually activate your account.

I hope to have this issue resolved soon.
