I have been trying to get this to work http://forums.pocketmine.net/plugins/namecorrector.1270/ However it is out of date, does anyone know of a simple plugin that replaces spaces in players usernames with underscores? It is becoming difficult for players on Windows 10 edition to join, as they can no edit their username without paying to change their xbox username. I don't know why this isn't built into MC in the first place.
