Setting another users attributes?

[Shorty2Dope]

How do you do it with NPC server or if it is possible, without NPC server.

ex: I want to set another users name. I would say "setname account 'name to give' "

I don't understand how it is possible to do.. if someone can just explain to me how its done and how each command works, that would be great

The only thing I know how to do is set the attributes of the player actually interacting with the NPC. I don't know how to tell the NPC to do something to someone else
