I have a problem with /nick. Two players can wear the same nick ! And I searched on the web, I don't see any solution provided by Essentials to avoid this. And I tried several plugins, but they prevent Group Manager prefix/suffix to be used.
Can you check this out and solve this issue please ? Thank you.
P.S. : when I try to put the last Essentials jar, my server stop to work properly. I'm using actually Essetnials 2.X SNAPSHOT and GroupManager 1.9.
Essentials 2.x SNAPSHOT
