first type "minecraft.net" into your search bar (without the quotes), then find where it says minecraft classic and underneath it says singleplayer and multiplayer. click multiplayer and up the top it should say download server software "here". the word "here" won't have any quotes though. hope i helped you.

We cannot make you a Minecraft server. We can only give you the map to play until you quit or you make a server of your own.
