I started a server with my friend several days where we just, kinda pvp. I have installed this plugin: https://dev.bukkit.org/projects/kits that we use to spawn kits to pvp. However, my friends needs an op to spawn kits, and i don't want to risk him destroying the server even though he's really bad with computers and with minecraft commands. I made permissions file, but i don't know how to give the node to him. Can someone help me?
