an array of players who touched a part?

I've actually done this for my game. Basically , create a int value object in the workspace called que. Then add a button for queuing up and un-queuing. The script for that should be simple. The script can rely on a que bool object in in the player so that when they reset their character it doesn't reset the value of it. Mine was much more trickky, because I had a label to show how many were queued and then also had a timer that counted down after a certain amount were queued.
