Warning: This plugin might not work on 1.8.3 and lower(I haven't got to testing it myself but someone had problems with 1.8.3). it is also very buggy and needs to be re done.
This plugin currently adds 3 new classes for you to mess around with on your server
This plugin is a good start but defiantly sill has a lot to go into it.
I'll try to update this plugin in this resource often.
Update to 1.9
