Also people should know if they don't already that you can massively muti table these. I had 16+ going at one point and with them being very push/fold it isn't too difficult to handle for most ppl.
I figured out there's a trick to it. Make sure upcoming/registering only is unchecked.
Click on one that's already full and it should say register to any. Click it, click ok and there should be a box that says ok or cancel. Now here's the main trick. If you watch the list, when they all move down one a new tournament has opened. Click ok and you're in every time.
Try putting the pop-up box level with the highlighted tournament and it's very easy to notice when it moves.
Good luck
