Operator

An Op, or operator, is a player designated to moderate a multiplayer server by the admin. This is done to help keep control of the server from unruly players and griefers, and even a reward to trusted players. People are made op by using the /op command. Ops have access to a variety of server commands which aid them in their policing duty. These are activated by typing them into the chat with appropriate arguments.

Ops also are granted the privilege of destroying and placing blocks.
