CommandBook or Essentials.jar (alone)? I personally use CommandBook, because it pWns, I wanted your guys opinion. Vote then comment pl0x!
Haven't used CommandBook (yet) will need to do so soon because Essentials is buggier than a $5 motel room. Total lack of consistency in installation and performance. So sad, looks great on paper, fails on a server.
Haven't tryed commandbook in a few weeks, but I really hated that theres no setting to disable the "X has turn time to Day" and stuff.
