How can i change a players user?

[aeroactual (clive)]

for example i’d want Player3 to say Mango1 or something
this is the error from trying to change it from explorer or script

 Label edit failed : The current thread cannot set 'Character's name' (lacking capability WritePlayer)

is there a way to get aroudn this?
