This is a bit off topic, but I have to insist that the use of screen names is not "hiding," unless it literally is, as in the case of RK, who has been popping up at various forums that he's been banned from lately with new screen names.

As the result of my own foolish use of my real-life first and last name in a a Usenet group some years ago, I was stalked, spammed, and received harassing phone calls from some anonymous troll there who took an intense disliking to me, evidently for being happier than she (assuming it really was a "she," which I don't.) It was a most unpleasant experience, and is specifically why I'm careful about who I disclose my full name to these day. To be fair, I've never had any such trouble in the Poser community, whew!

By the way, cooler has posted his real-life name numerous times in Renderosity forums.
