Might I also suggest that once most people start shipping, we don't publicly state if/when we have (or haven't) shipped? That's another way people easily "figure out" who may (or may not) have been their SS.
Mine's not too difficult, being the only one that will have a customs label on it. It was great a couple years ago, when I was able to hop across the border, and ship directly from USPS. No such luck this year though.
