oh also the permissions i added are as follows:
spawn.set - Allows admins to set the spawn
spawn.admin - Allows admins to send other players to spawn
spawn.use - Allows players to use the spawn command
spawn.bypass - Allows players to bypass the teleport delay

 

You're welcome. I may make a few changes to clean it up a bit, but i will make sure to forward them to you so you have the most updated version
