This is the command that lets you do everything in one command. If you leave any of the parameters blank it gets set back to the default value. Only the player name is necessary
Sets or resets the player's nickname
Sets or resets the nickname's color
Sets or resets the color modifier of a nickname
Colors can be found here; you MUST type them the same spelling as they appear: http://jd.bukkit.org/rb/apidocs/org/bukkit/ChatColor.html
"Color mods" as I call them are italics, bold, strikethrough, underline, and "magic"
Gives access to all the commands
Lets you set your own nickname
Lets you set other's nicknames
All permissions are given to ops by default
If you find a bug, or you have a suggestion, let me know and I'll hopefully be able to fix it/consider your idea
The databases for version 2.0 and any previous versions are incompatible, sorry. I had to swap to UUIDs from player names.
