Away-From-Table
In tournaments, you may not "sit out". Instead, you are set "away-from-table," meaning you are dealt into every hand, post blinds when it's your turn, and then fold when there is a raise before the flop, or a bet after the flop. When you are in an online tournament and need to leave or lose your connection, you are automatically marked as "away-from-table."
