ProSpawn
This plugin/Skript adds a /setspawn plugin for operators to do on your server! Since it is so lightweight and under a Kilobyte in usage, it makes it easier to run your server with this rather than EssentialsSpawn or another spawn plugin! Simply do /setspawn and then whenever a player wants to go back to that spawning location they can do /spawn!

This also works for on first join and on join! All players will start at the Spawn of the server! Also, this Skript is configurable once put into the files and can be edited!
