I wish all of you the best in building a bankroll from nothing!
A few suggestions that may be different than others have said.
I would NOT focus on 1 site,give yourself as many opportunitys for success as possible.If FT for example doesn't have a freeroll now but Bodog does then jump in there at Bodog.The more chances you have the better in the long run!
If you happen to win some money,I would add 1$ tourneys to your arsenal of tourneys that you play.So what if you lose the few bucks,What you are trying to accomplish is to hit a good one to allow growth in your bankroll.
If you go Broke losing $3 you won so be it!Don't play scared.
I will give you an example,I signed up at Carbon poker through CC and got 2nd in a freeroll for $25,I then played an $11 buy in (CC money added) and won that making my roll around $135.My bankroll from all accounts allows me to make this jump and still be good bankroll management.The lesson I am trying to give is tourney poker can pay off handsomely.But you have to be willing to risk some of your freeroll winnings!
Once you get to $75-$150,I would add $2-$3 buy ins and around $250 I add $5 buy ins.
Do not get frustrated with lack of bankroll growth in the beginning.The experiance you get is going to be needed as you grow as a poker player.
Hang in there,when you do win your account can jump quickly.
I have a few other Ideas I will post later,this is getting pretty long for me.
