Stolen thread title imo.
I'm doing basically the same thing on a couple of sites. Problem is there aren't enough freerolls at a time I can play to make it worth while. If I hit on a few I'll get more serious about it and grind some nanosngs too.
Also built my first roll on stars this way. Was up to $25 until I had my first lesson in bankroll management and busto.
Gl, hopefully sooner than later we'll get the right to play back and get to grind for real.
