FULLTILT POKER withdrawl question

I play in tournaments nightly on fulltilt that cost 500k play chips and u win real money....if I take the money and build a significant bankroll does it have any withdrawl stipulations like winning money from freerolls

I believe FT like most sites requires at least one deposit before they will release freeroll winnings, but I can't swear to it. I've had great cashout experience with them, but I deposited from day one.
