People who don't have computers.
Play it on DAT XBOX or iTouch/iPhone or Android phone!
I never played Minecraft. So this might be a noob question how do you actually connect? Do you need the offical client?
Well, I'm guessing Ozfers server is a legit server (as in not a cracked server) so you will need to create an account on Minecraft.net, then purchase the game. Download the client, then add the server under multiplayer. You must know the IP address. Enter the IP followed by the port. EX. crapserver.no.ip.org:25565 OR 188.8.131.52:25565.
If it's a cracked server, you need to get either a cracked client or a actually buy the game as well. *Sigh* To much info! You don't have to pay for the game if it's cracked.

Make sure you force update the first time.
Just enter the IP address and port number (25565 most of the time) and boom!
