U can make a hierachy in the chatroom
something like this:

Administrators(the can ban people from the chat )
INFO-ers(the can give INFO about the game )

and at the bottom the Game Players(the arent able to do a thing)

the Admins(Administrators) are able to give Game Plaerys a UPGRADE.
That is from Game players to Admins.
This is only for the Admins.
And the Admins are marked RED.
And the INFO-ers are marked GREEN.
it will look like this @shadowgirl12
@stands for Admin
#stands for INFO-er

Hopefully u will add this at the chat
