Out-freaking-standing! I didn't know about seclog so learned something new; I changed my password a few days ago and sure enough it showed up in the log.

One quibble, though, is that entering "r=" or "/r=" (with or without quotes) into a Google site-search or the forum's native search just returns results for "R" and that, of course, is totally useless. At least it does so for me.
