I have a question that just doesn't seem easy to put to words in a Google search, so here goes.
There's only one computer in the house. My brother and I play Minecraft on it using the same account. Up to this day, I play on my world, and he plays on his own (which just so happens to be the same seed, thereby the same world).
I want to know if it's possible to turn this world into a local server (or just recreate a world and make it into a server) and then have make it so that he can log into it and build things. Then he logs out, and I log into that same server, and see the progress he's made, and make my own. In essence, we wouldn't be playing at the same time, but we would coexist in the same server. Is that possible? If so, how? Thanks.
