I think a couple of teams begin Tuesday. Then the rest of the league starts the following Friday or something. But you'll need to set your lineup by this Sunday the 23rd in your Monday the 24th slot. That should set the entire week, but check to make sure. So set it on Sunday in the Monday the 24th slot. I'm pretty sure if you set it in the Sunday slot it won't work...You can set it in the Sunday slot too just to be sure though.

Let me know if anyone is confused.
