Why not also disabling the use of putting names in nickname place? Like you guys did for the parentheses "()"
So add it as
if (this.text=clientr.staff) {
this.text == "";
}
That might help for the people copying staff names... (P.S: I suck at scripting but I hope you got my point)
EDIT: if you didn't understand, that means putting "snk" for example in your nickname will get deleted automatically.
