I am making a plugin on my server it is going to be finished soon but until then anyone can start making the world great for free. No give no block protection and soon to be leveling system that helps with breaking blocks or give you more health.  Suggestions would be nice.  Anyway free server with no current mods and future mods will probably not give block protection.  PVP the game the way its supposed to be.  Build your house and hide your stash and prepare for the leveling system and clan system ahead of time.
