I get a lot of people that register via others, and then never show up... I tend to right click and undo the buy-in from the tables tab, but no undo buy in. Not a HUGE deal, just preference, I guess... Would make for less mouse clicks when I remove the deadstacks... When I remember, I undo the buy in (which removes them from the tables tab completely), then have to go to the players tab, look for their name (or for who doesn't have a point since they haven't bought in anymore), and remove them that way.
