It has come to my attention that at least two users of hotmail are having difficulty receiving email from the server. I am investigating the issue at this time, and hopefully will be able to clear it up; however, please be aware that Hotmail does this from time to time, and I must recommend against the use of that service.
Now, I hate it when people say "So, the solution is to change what you use!" — so I emphasize, this is just a recommendation. But hey, I'm doing my best. They're difficult to work with. So I'm still recommended you consider how much important email you might lose… and then use whatever you like.
But at this time, problems are known, and I'm doing what I can.
EDIT: So actually... if you have a hotmail address, send an email with your username to the email address in my signature and I'll manually activate your account...
