IslandPlots is one of many few completely automatic Plot Plugins, I'll explain why this is so useful...!
Many Large Servers like to offer Donator Plots, although it can be a very tedious process having to manually define each plot for a user, and having large Flat Land Worlds for plots, that can ultimately increase lag. This plugin is efficient, and adds a new light on Donor Plots or Plots generally, how it works is as follows: Plots are Islands, and users can create their own Plot Island, with a single command, these Islands come in two Sizes (Small/Big), and don't generate many chunks at all. Island Plots can be reset, visited by Admins, deleted, visited by fellow players, and can toggle PvP. A upside for Large Servers, is that an Island is unloaded from the Server after 3 Minutes of a player leaving it, this makes the plugin more efficient, as no resources are being wasted for Islands that have no players on them.
