OK, I'm new here, so please pardon my rant. Am I the only one who thinks that the read receipt pop-up when sending PMs get annoying after a while? It's nice to be able to track messages, but not only is it confusing ("Cancel"? Cancel what?), it is also a waste of a click (or a keystroke). Please let me know I'm not the only one who finds this annoying... (I made a trip to the vBulletin forums already to find out how to disable it, but that's up to the admins.)
