If anyone is thinking about signing up, here is my link. The cool thing is once you are in, they have a referral system where you get a (tiny) kickback of the money your referrals wager each week.

They are running a promo (I think until the Sunday games kick off), they will match your initial deposit 100% up to $200 which is a great deal. I only signed up for $50 to try it and wish I had done the whole $200.
There are tons of promo codes out there if you Google it, I know one is FFML.
I figured if we have a decent amount of people playing here we can talk strategies each week in this thread. You only have $60,000 to spend in your salary cap and the studs like Manning and Calvin Johnson are in the $9k-$10k range, so there is obviously some strategy involved in how you structure your team.
