Sure they have been down a lot, but they offer a great product. I was shocked when my friend who does Yahoo said that they can not even have minor leaguers on their rosters.
I would reccomend trying cbs's Fantasy Commissioner. I have not had nearly as many problems that are nearly as severe as the ones most of you have spoken of. And even if the site is down when it is time to set your line-up, which has only happend 1 week out of 21 in my league, as a Commissioner, you have the ability to modify an team's line-up, for them, mid-week.
All and All cbs is not as realiable as I would like them to be, however I am yet to find a better all around site for running my own league.
