grenv: But that requires planning in advance. I use auto vacation because I don't know the exact dates I need them. It will depend on when my opponents in the games with the fastest time controls will move - if I play a game with 4 days/move, and I'm away for 7 days, I may need 0, 1, 2, or 3 vacation days, depending on when my opponent moves. I don't always know when I will be back. And after coming back from vacation, it may take a few days to make moves in all my games, depending on what other pressing things I need to do, and how many games I have to move in. Autovacation is just much more convenient. As for "dragging on tournaments", I don't experience that. Whenever I look at a tournament that has been started a long time ago, and hence is "dragging", it's always because of active games, where people actually move. Note that with vacation days, and weekends, a black rook (assuming he's not bought more vacation days) can only "drag" a tournament for at most 2 months by not playing. Then he's out of vacation days. And she can only do that trick once a year.
Note also that Fencer has pointed out that in the future, autovacation will be the only vacation. But that's all I know about the rewrite of BK.
