I signed up for paperless billing on my T-Mobile account:
Fail.
In unrelated news: My web hosting company decided to move all my servers at 2 AM yesterday morning, completely breaking every server I had, including email (which bounced), web services, everything. And they notified me…. by email. At 2 AM on Easter Sunday. And then, apparently, they took the holiday off, because I submitted my first support ticket to them at 5 PM when I found out about the problem, and have not yet had any kind of reply from them. Although most emails seem to be going through now. Maybe. I hope.
