S.O.S

I need help! I need 4 station masters for the games during class trip. Your job is just to ensure everyone plays fairly and just basically watch the game =D So if anyone doesn't feel like participating in those games, kindly let me know so I'll brief you on what to do. Those who are station masters can't participate in the games btw. Oh and I need some ideas on any interesting games to play too. Let me know! Thanks ;)
