Well for me signed up because i was bored out of my fuckin mind and to be honest the whole world is bored out of there fuckin mind if you can entertain them a bit you will get sales.
But if you gonna try to pull in poeple under you well i suggest you first try to get some deal with the admins of the sites,full tilt and pokerstars and partypoker are great when you have your deal pulled in just make it a big deal so for example if the person in question get double of first deposit say something like:Don`t hesitate to make your first deposit now and if you use this or this voucher you get even double your money thats right double of your investment to win your first 1 million $ poker event don`t hesitate and act now! everybody can win!
Well you get the point.
Anyways much luck.
