Lua? Help? Possible?

Hi i want to learn lua but before i do how do i make a addon, SO when a staff removes rank from owner
the owner does
!key {KEYINCONFIG}
and i will run command ulx adduser Mitch Owner
KEYINCONFIG i could set it to anything
Your going to say why don’t you use rcon. well, rcon is somethimes hard to get to with forgetting password
would anyone make it?
Ik you could crack it but all i need is a script to put in autorun right?
Thanks for the help

Use rcon. Write down your passwords if your head is full of holes.

RR but i want to make it so i can add a key for vip so when a a user joins so i dont have to join and give it to then all they do is !key 1234
