If you are doing a money league, with a lot of screwy rules, and crazy scoring, like my league, check out myfantasyleague.com. They are small, much cheaper than CBS, and have options I have NOT BEEN ABLE to find anywhere else.
This is our first year using them, but you can literally set up your league for free, test it, check it out, an pay right before the season starts. The commish also gets a free subscription to footballguys.com. You can run a 20-team league, auction league, do a waiver or bid system, salary cap, and do any scoring plan you can imagine (including coach points). And, best of all, Live Scoring!
I had it with sportsline, the live scoring (the feature you cannot live without) is screwy the first 4 weeks of the season. The support staff is lame....this new site has a support message board that the admins check all day long.
Oh, yeah, this site allows for doubleheaders every week--you can have two opponents every week, so instead of 13 games over 13 weeks, you play 26 over 13....
