Has a website ever asked for a contact e-mail, and when you entered it, it told you that e-mail wasn't available? WTH is that? I'm not signing up for an e-mail, I'm trying to use that e-mail, idiot.

@dr_zooks yes. I had to use an alternate email address for one of my monthly bills. It kept telling me the email I wanted to use was invalid. Very frustrating. I still haven’t gotten it worked out.
