Just sent you one.
Also, to make things clear, PM problems primarily arise when your username and display name don't match. Say somebody signs up under the username "Jeff," but with the display name "Crap Muncherson." Meanwhile, somebody else signs up with the username (which is unique to you) "Steve," but Steve posts under the display name (which is not necessarily unique to you) "Jeff." If I try to send a PM to Jeff, Crap Muncherson gets it. Two usernames are a stupid design flaw for this reason, among others. To remedy this, I change Jeff's display name to a unique name of his choice, or if the other poster isn't active and never made a post, just delete theirs so Jeff can receive PMs freely.
