I kind of made it up. On a lot of clients now when you click on somebody's profile it has a Zap tab that shows who Zapped and for how much. I'm calling that the ZapWall. Top Zpot. Someone else is already calling it Top Z lol. It would be cool if it became a thing and people were competing for top Z. And the winner would be the person getting the Zpot and the person getting the Zap
