OK, something fairly strange and suspicious just happened. The site went down and came back up, and after it came up, I wasn't logged in. No problem, except when I went to log in, I was told my password was incorrect. I tried a few times to make sure there was no typo, then I clicked on password request. The e-mail I received from password request showed NO username and something that was definitely NOT my password, and trying the "new" password didn't work either. A few minutes later, and I was able to log in with my normal password. I think the site may be under attack, and the attacker is trying to mine e-mail addresses (and succeeded in getting mine).
