I've played on here a fair bit in the past. Played in the student poker tour, was a freeroll each tuesday for about $500. Only about 100 people were playing in the first few weeks, then about 250 towards the end.
I've come 2nd in a freeroll too, was quite hard cus it was full. The winnings were something like $8. I spent it on the next tourney ($2 dollar Multi table) and came first, won myself about $80.
I spunked it all though, then asked them to ban me from play cus I was gnna start to deposit. I can still play free money / freerolls, but doesn't have the same kick.~
(I have a bad history with online poker, was pretty much hooked at 17 - blew most of my xmas money on UltimateBet).
