After long last, I have now uploaded a more recent version of my Main 1.0.0 world. You can find it on the sidebar, or using the link below. This new version has many more things such as the Nether portal room, a potato farm, Nether hub, and 1.4.x terrain. I haven't been on this map very much, kind of getting bored with it. I might end up starting a new one.
