I am a server admin and i am looking for a plugin for Creative world that automatically would create plots like a 50x50 land of grass with a small wall, and any player would just type /plot claim and he would get creative gm and could build only in his plot.
I dont know if its what ur looking for and I never tried it, but the world generator InfinitePlots http://dev.bukkit.org/server-mods/infiniteplots/ in combination with InfiniteClaims http://dev.bukkit.org/server-mods/infiniteclaims/ might do it... Im not sure about getting gm though. EDIT: I think giving anyone who joins the world gm should work, it looks like infiniteclaims protects the plots so u can only build on ur own plot
