If you have an email ending in @hotmail.com, @live.com or @outlook.com (or any other Microsoft-related domain), please consider changing it to another email provider; Microsoft decided to instantly block the server's IP, so emails can't be sent to these addresses.
If you use an @yahoo.com email or any related Yahoo services, they have blocked us also due to "user complaints"
FYI our server needs to be moved, and thus the site will experience a short period of downtime. It is estimated to take a couple hours or so. Most likely it'll be tomorrow (Sunday) night or Monday night, eastern time.
