I want to sell a new group permission, but then also have it chat the user with the commands he can run.

how can i do this

nevermind, figured it out.

how does one do this so it removes it after a period of time

Can you share?

for the multiple commands, just add another line in the json array

      "commands": [
        "specialplayer $player.id",
	"pm $player.id \"You now are special.\""
      ],​
