I think and hope that there should be a new command added to all EMP servers: /personalnick (or) /pnick. If your friend has a loooong username, and it's frustrating to even have to remember it, use this new command. The way it would work: /pnick [player's name] [nickname]. When nicknaming a friend, you can type /tell [nickname] [message] and that friend would get the message. These nicknames would be restricted so only you can see it.
