I have created a project i call DropBlox.

what is DropBlox? Well it is a system to easily add a building and structure for the world to see. Just download(link) click on hamachi.pkg install hamachi then go to server.properties and where it says server_ip type in your ip(it says it on hamachi). Then run start.command. Finally type in the same ip that is in server_ip.

Add your building ass many times as you want and the next person to go on it will see your building.
