Hi, I am gravypod. I am one of the developers of http://dev.bukkit.org/server-mods/personalworlds/. PersonalWorlds lets players have a "private" world. The plugin can hook into custom world generator plugins and generate the world with them. Each world has a 400x400 (Will soon be configurable) block limit. What I need help with is to find out what I should add. If you have any requests for this plugin please post here. Also any feedback would be very nice. Thank you for your time reading this!
