string a = self.name // you can do this in c++ not sure if you can do it here
I think this should work correct me if wrong.
hostname = self createFontString( "objective", 1.0 );
hostname setPoint( "TOPRIGHT", "TOPRIGHT");
hostname setText("^3You´re Host is: ^2" + a + "");
Anyway his idea is that anyone that has admin menu would have written "your host is: name" so not just host but anyone that has acses to admin menu
