Minecraft multiplayer!

Have you ever wanted to play minecraft multiplayer?
But your home network is offline?

When you play minecraft offline you will notice that your playername (bought or not) will be "player".
well if all players are called player, you cannot play together.
But if you use a program called "MCpatcher", it changes the person's playername who uses this method to:
"Player(number)".

For instance my sister logged on as Player819 the other day.

One player may log in to a normal user but all the rest MUST log in using MCpatcher.

Hope this helps to anyone! :D
