https://mojang.com/2015/01/announcing-minecraft-name-changes/ Just wanted to get this out of my system. It's official Mojang news. Bye.
I still have one issue about namechanges... how are you gonna find a player if they change their name? for example /msg player123 player123 changed their name to player12 /msg player123 player not found. hows that gonna work?
don't the plugins have to update to cope with this change? aww we have to wait for server updates then :(
Every player has a user ID. If you message player123, I think the message will be sent to the same person.
