Ben, I've been doing the roll call thing for awhile now and honestly dont know how it works either. I put my name there, copy, paste, say something silly, screw around with some of the knuckle heads sometimes and make a promise. I haven't pussed out on that promise yet so the thing works. People cared about my quit early on and they're still hangin around too. That helps. It's the only thing I've ever known that worked. Part of the reason is the community of like minded folks imposing there quit will on you but the will comes from within first.
If you don't believe me, there are a bunch of quitters that can confirm.
Are you ready?
