I searched everywhere to make one! MinecraftForums, Minecraft Wiki, IGN, etc... AND I CAN`T SEEM TO FIGURE OUT how to check "Online Game!" I am logged in, I have live, and It won`t work! PLEASE help! I wanna play with people!
Yeah, sounds to me like you don't have a Gold membership. You can't play online with a Silver account. All multiplayer requires an Xbox Live Gold membership.
EDIT: THAT IS MY USERNAME MAN
