An old server called Pigsaddle used this plugin. It's described in the bullets below. It is a grief protection-type plugin. You use a golden shovel to claim plots. Once a plot is claimed, only you and administrators can modify it. You can use commands like /trust [Character name] to allow that user to make modifications to the plot. The plot was arranged by [Number] x [Number] , infinitely claiming all blocks directly below and above it.
