Hello, Minecraft players,

Two years ago I bought Minecraft, and I loved it. The Minecraft game itself is amazing, but in my world called: Morton's Country, I created a city, cities, houses, rollercoasters, high work buildings, skyscrapers, annd what more. Everytime im there I can't lose my way. I know where I live, thanks for all of the signs, maps, and buildings that I built. I still love my world. A creation of a civilazation hunts me. I want actuall people- I want to have fun with the real feeling. And, Is there a mod for civilazation? Can I make my world a server? If I can- How? How do I make my world a server? How do I make a server? Where can I find mods that work?(I know there are mods in this site, but windrift stopped its trial for me)Please- Help me! I want to actaully have the real fun of minecraft. Help me find it.
