It's about a mod called Minecraft comes Alive. You can take a look at the original forum. I'm kittyjane there. I mostly comment to help people out when they have trouble with the mod.

The mod is about that these boring, fat nosed testificates will dissapear. Then replaced by actual humans with designed skins from people all over the world. Your skin might appear in next update tho. And they have genders displayed by their skin. You can marry them and have a child growing up and passing on the heritage. You can look at minecraftforum.net for more information. Because there is more stuffs to do than raising childrens and so.
