I would like to be recommended a plugin that does the following. * Admins can create plots for users to purchase * Users can purchase plots by right clicking a sign * Users can add mates to their plot * Users can put their plots up for sale
I'd say you could possibly use PlotMe. Villages (http://dev.bukkit.org/bukkit-plugins/villages/) has features like this, but if you don't want the town side of things, stick with PlotMe.
