1) u can unregister up to, but not later than, 10 mins before gametime on stars
2) for the same reason as Zy's, im gonna wait to register before the tourney stars, just to make sure i have enough funds. main reason being, WPT bahamas sats actually end very early this yr-dec 11!-so im gonna stop being lazy and step it up next couple of days. i only entered 4 of them so far (2 cashes/near seat bubbles), and thats not enough.
