alanback: As we're both Rook members, you might not realize what happens to Pawn members when playing a Rook member that uses autovacation. I'm playing his opponent in a game of Dark Chess that has a four day time limit on it. The time has run out three days in a row now. As you say, it just adds another day to the time and doesn't time out the game. A right nice feature if you ask me, even if it can be abused. The advantage of being a Rook member is having unlimited amount of games if I choose. A Pawn member has a 20 game limit. If he's playing a few people that move slow and a few that are on vacation, that doesn't leave many games to play. Some people only log on once a week or so, so it can make for some slow games if like to play a move a day. This is why it can be frustrating if your opponent logs on, but doesn't move in your game. As I said earlier, when you have hundreds of games going it takes awhile to get to them all. Even if you play games that don't require the study that games like Dark Chess or regular Chess do, a lot of games is still a lot of moves to make. His opponent is also playing those kind of games besides Backgammon. I'm sure he studies the particular game with me a lot, though the stage it is at now will begin to move a lot easier than just two moves ago because of what has happened in the game.

I'm not sure what you mean by only being used once. As far as I know, you can use all of them consecutively until you use them all up.
