Minecraft Servers and Joining

In Minecraft, you can play multiplayer online with an internet connection. The attached video will show you how to create your own server. 

In some Multiplayer maps, you get unlimited blocks and supplies.But if not, here is a way to get more blocks:

 If you are an op, (see Multiplayer ops) you can give items to other players if you want. In the server window that pops up when your playing, type in give, then the players name, then the item number for the block you want. there you go. then just minimize the server window (do not exit out of the server window!) and go back to playing minecraft.
