the only thing i can think up would be have everyone submit their ideal roster (complete), but obviously have more than one player for each position, (i.e. pick 5 1st basemen, 5 2nd basemen, etc.); rank them in the order in which they'd select them that way if someone doesn't log on for a day or so, you could see that so-and-so would have picked jeter in the 2nd round and you could just place him and the draft could move on. i'm not sure how practical this is from your perspective (as moderator), but it's basically all i thought of, haha.
