I think I've seen this problem mentioned before, but I don't see a thread for it, so I'll make one. 

 

Bob Bressler sent me a private message earlier that never showed up in my inbox.  I got the message via email, bearing his email address as the From field, but no sign of it anywhere here on the board.

Edit: Oh, wait, I see that there's an email link on the user page.  Bet that's where it came from.
