How do my friends join my LuckyChunk server?

You get a server address when you create your server. Send it to your friends. They open Minecraft, go to Multiplayer, click Add Server, paste the address, and they're in. They don't need to make an account on our site or install anything. If the server happens to be asleep, it'll start up on its own in about 20 seconds. Full walkthrough with screenshots in our How to Join a Minecraft Server guide.
