i think we can make a command which will make the players change there names faster than applying to change the names.
and i got a Good command here is it.
/changename
and when he change the name every thing will be auto changed to the new name of the player.
example:
player name: Hunter
and this player have a car and house,
then he made /changename HunterPro
his car and his house will be auto changed to his new name.
this is my idea and i hope u like it.
