But, on first deposit, or every deposit?

A referral program is always more attractive when it has the possibility of recurrent gains, like 30% of house hedge forever, the immediate gain for the affiliate is lower, but on the long run it will probably be higher, this will not invalidate some reward on first deposit.

More freerolls will be nice, specially at more friendly hours for us across the pond, it's quite late here the current daily freeroll of Hedge Poker, and has I've been seeing in other bitcoin poker sites, freerolls seems the way to get an active user base.
