Getting onto Minecraft Multiplayer is very simple. All you need to do is when you get onto Minecraft you click "Multiplayer" instead of "Singleplayer", "Mods and Texturepacks" or"Options" and type in the Multiplayer IP (which you can get from the Internet or a freind) and click "Connect".
There is no fake Minecraft, but you need a paid account.
You have to pay for the full premium version which includes multiplayer, however free users can play multiplayer on Minecraft Classic.
