Hi Players !!!!
I make this plugin request because I found the plugin in spigot mc !!!!
There is a plugin for manage chat and permissions !!!
Is 1,000,000 easier from PermissionsEx
There is the link
https://www.spigotmc.org/resources/groupmanager.23/
Thank You !!! 
They can't add group manager and it has already been denied multiple times. Sorry
But.... there´s in spigot mc !! 
I think they said it's not directly available. I'm sorry, I forgot why they denied it.
It's only available via external site, so we can't add it.
