Got to basically have your mouse over the register as soon as FT's clock hit's the the open for regrisration time. They fill up in less the 15-30 seconds easily. It's basically a race to who can get in quiclly. They run like every 4 or so hours apart.

BTW - I picked up this weekend a great little program that works for free rools in the demo version. It called Tournement Indicator.
