I agree with promotions and free rolls but players must not be allowed to play free-rolls ONLY.
I see the poker sites where all the free-rolls table are full and the ring games section and other tournaments such as Sit-n-Go are empty. So a condition must be enforced for playing free-rolls one must deposit and play ring games also.

Do you mean luckyflop? Luckyflop is a new site, need more time to attract more customers. If 200 players online there, I think SNG and Ring would be full of players.
Freeroll is aim to attract new users. If it sets some thresholds, why people play there?
I see a good example is betcoin, it has 2 kind of freerolls. One is for everyone, the other one is only for deposit users, prize if also bigger.
