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 the following 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.

Commands

 * /op - makes the player with the typed name an Op.
 * /deop - removes op status from the player with the typed name.
 * /kick - forces the player with the typed name to disconnect from the server.
 * /list - displays a list of connected players in your chatlog
 * /ban - bans the player with the typed name from the server. They remain banned until the /pardon command is used.
 * /banip - bans the player with the typed name via IP address. This allows admins to prevent people who use alternate accounts to circumvent bans, but should be used in moderation, as it prevents any other person using the IP from playing in the server as well; this can be frustrating for people playing from school or library computer labs. Banip does not block the account itself.
 * /pardon - removes the ban on the player with the typed name, allowing them to reenter the server.
 * /say - functions as /broadcast, but in a shorter and easier to type command.
 * /tp  - also functions as teleport, but with a shorter, more useful command. e.g. /tp bob jim will teleport bob to jim.
 * /solid - allows the the op to place unbreakable blocks, only ops can remove unbreakable blocks.
