This plugin is standalone and has several cool features not seen in other nick naming plugins.
For now: download the .jar file found in target. I will streamline this eventually.
/nick [Player] [New Name] - Changes the target player's display name to the new name. Supports these color codes
/nick [New Name] - Same as above, but a shortcut to change your own display name.
NOTE: /color and /colour both work in all below commands.
/color list - Lists availiable colours.
/color [Player] [Color] - Changes the colour of the target player. Name is unchanged, only the colour changes.
/color [Color] - Same as above, but a shortcut to change your own colour.
/reset [Player] - Resets a given player's name to the default minecraft name.
/reset - Resets your name.
/realnicks - Lists online players, showing both their display name and their true identity.
