I run a 2 QB league on ESPN which may go keeper after the 2012 season. I can't make any promises and it would only be perhaps 2 - 3 players who could be kept, but we have a really good core of managers (experienced, mature, 7 of 8 returning). The buy-in is $100 and we will draft on September 1st at 1:30 pm Eastern (it's a Saturday).
Let me know if you would like full league details. I should also note, since most of the managers are friends, colleagues, my brother, we don't use Leaguesafe. However, I can send you the payment details via my corporate email address, that way you know who I am and where I work.
I would love to have you join the league, I have been looking for someone to fill the 10th and final slot now for a good 3 weeks. And someone with your experience would compliment the rest of the managers, most of whom have 5+ years of FF experience.
