Well, you can't give yourself rights you don't have, nor give them when hiring.
And about the npcserver, I assume you mean when someone pms or sends a masspm to the npcserver:
In the onCreated event in Control-NPC, use
PHP Code:
// Example
function onCreated() {
setpm("Hi, you just sended a pm to me, but it was in your native language so I couldn't translate it, try again later.");
}
