Okay, this isn't a major problem or anything, just something I thought was weird. When I delete a private message, instead of saying, "Thank you, TheCow, for deleting this message," (or whatever it says), it says, "Thank you, [some number], for deleting this message." I'm not sure what the number is (maybe something relating to the database of names?), it's just kind of odd.
I was getting that behavior too. I kept meaning to mention it... There was a point, actually, a month or so ago, when it went away; then it started happening again a week later and I kept meaning to mention it... Thanks, though. Much better now.
