Sometimes when I'm in the tower, something comes up and I need to get off the computer for a while. Usually if I'm staying home, I won't log off Aces High.
The wish is that after about 30 min of no activity (moving the mouse or clicking on something), you would be marked as AFK so that people wouldn't be trying to talk to you while your gone. Also, when I get back I always forget to uncheck AFK and people still think I'm gone. When you are active again AFK should automatically be unchecked. If someone wants to play and still be marked AFK for whatever reason, I guess there could be an option for this feature.
