Um... it's not hard to find what withdrawal rules FT has http://www.fulltiltpoker.com/withdrawal
Edit: Dang, sorry they don't list all of the options nor each options limit. Probably have to look in the cashier for that and they probably change over time.
Edit 2: Yep you have to look in the cashier at each separate option
What is the minimum amount I can withdraw?
The minimum withdrawal amount varies by payment processor. You can find the minimum withdrawal amounts for each payment processor on the “Withdrawal” screen in the “Cashier” window. If your available balance is less than the minimum amount, please contact firstname.lastname@example.org
for more information.
