The forum freerolls have a much better payout than the straight poker site
freerolls, as you have found. Look around for others that pay more than 1% of the players for a better chance at increasing your bankroll.
Realize that 10 cent tournaments are risking 10% of your bankroll. Since it is only $1.37 that might not be a real problem since you can always start over. Also, the people who rebuy are going to put you at a little bit of a disadvantage, but since the rebuys are 50 cents, that mathematically makes up for it. I wish you luck at that.
