This one may not appeal to as large of a group, but I have set up a fantasy group to play in the Masters Best Ball Challenge. The link to sign up is here. If you're interested, check it out. If not, don't worry about it. I can deal with your rejection.
Update: I am now making a strong comeback in my NCAA Tournament Challenge. My poor choices early in the tournament found me in last place after the second round (even behind Betty Clair, who picked Boston College solely for their initials). However, my more careful selections in rounds 3 and 4 now have me tied for second place. Click here for the scoreboard.
