I would have liked there to be rules for names: Only ordinary characters and numbers should be allowed (I believe Koreans use Arabic numerals like we do, and that they have them on their smartphones).
I'd also like there to be a minimum and a maximum number of characters for names (including squadron names):
My suggestion could be a minimum of three or four characters, and a maximum of say eight or ten. There can be no real need for longer names than that, and some maxi names really clutter up the screen.
A rule like that could be enforced automatically for existing users by substituting #-s for "illegal" caracters, by adding #-es to names that were too short, and cutting the last characters in names that were too long.
I played against someone yesterday who had a name consisting of I think at least 15 underscores and some spaces and numbers.
He probably used the underscores to make it more difficult to locate his plane.
His name filled up I think three quarters of the screen and really made it difficult to see where he was, and also to see the other players in the game clearly enough.
