Want to make a simple Skript queue that is fully configurable, countdown, max players, and teleports when the countdown is over? You've came to the right place!
Commands:
/queue Join the queue
/leavequeue Leave the queue
/startqueue Start a queue if the script is bugged
/setqueuetp Set the teleport for the queue (where you are teleported after countdown)

Permissions:
queue.start
queue.setteleport

PLEASE CONFIGURE MAX PLAYERS AND COUNTDOWN IN THE FILE!
