We're currently seeing a lot of registration/verification emails to hotmail.com and msn.com addresses bouncing back to us. We suspect a majority may not be getting through. If you've recently signed up with a hotmail or msn account and didn't receive your confirmation emails, please send a message from the account you signed up with to us, and we'll be able to help you.
We are working hard to try and resolve this issue and apologize for the inconvenience. If someone has heard of this problem before, and/or know of a solution, please let us know.
EDIT: This still seems to be a current issue. We've also gotten reports of any email related to AOL. So if you are not receiving email responses from us, and you have any of these email addresses: aim.com, AOL.com, Hotmail.com, msn.com, please change your email address and submit a new ticket. We suggest you go to http://www.gmail.com
and create a free account, as we seems to have no trouble with these.
