BelgoSuisse would be the one to talk about building a bankroll from nothing, here, as he actually did the Ferguson Challenge and went from $0 - $10,000.
Me, I've went from $0 - $450 by following correct bankroll management and the advice from some of the best threads here.. but ended up losing most of it by straying from that path and entering into a lot of the MiniFTOPS games last year in the fall, and not cashing in one of them.
Two of the best freeroll games to get into on Full Tilt Poker
1) CardsChat Freerolls: Absolute best freerolls there are. Good quality players with an average of 130-150 players during our Tuesday and Saturday freerolls. They are $200 freerolls that usually pay out the top 18, sometimes top 27 if there are enough players, and the first one out ITM gets $2, with the winner getting either $46 or $54 (again, depending on the amount of players)
2) Full Tilt Facebook Freerolls: Full Tilt's facebook holds 400 player max $100 freerolls. About 10% of the field cash, and would give you a nice little addition to your baby bankroll. You have to keep an eye out on their facebook.
