I have used Yahoo! before and have not been disappointed. Please feel free to use FanPosts or FanShots to update everyone on the status of your league, especially if you want to flaunt your scores. God knows you will probably do better in your league than I'll do in mine.
If you have questions about how to set up a good league, contact Matt and he can give you some great pointers.
Yahoo! Fantasy Football supports SBNation.com and fantasy league families everywhere. In addition to the great drafting, trading, scoring and research that makes it the #1 free fantasy football game, this season also features a brand new mobile app and Pro Leagues, where you can compete for cash!
