This is my first little Plugin. It displays all players that ever visited the Server. This is only working for Admins.
Commands to enter in the chat:
|/lisplayers||Lists all players in alphabetic order|
|/listplayers last||Lists all players in order of their last login time|
|/listplayers total||Lists all players in order of their total online time|
Special thanks go to Minotorious who helped me out with an essential part of source code.
