Example: Username (from Minecraft original launcher): User123 Once connected to the Minecraft Server utilizing Bukkit it will first check if an Alias for User123 exists, if it exists set it, otherwise login and display a prompt stating they can create an 'alias' then load world for player. If anyone knows if this exist I appologize in advance for re-posting. Otherwise if anyone has any ideas on how I could get started on a plugin such as this that would be just as good! Thank You
