Years C: Adding aging to minecraft. You start off as a kid, that is around 1 block high.
Family C: Adds the ability to create family units and be a girl to minecraft.
HD skins mod: A mod that as the name suggests, allows you to use High definition skins for you, the player. You can use it by signing in to Jins website and go to the "MORE" menu. You will see a "HD Skin Upload Page" link. There you will be allowed to upload an image, that has a WAY larger size, then even a 512x512 resource pack! But the best thing about this mod, is that compare to a resource pack is that other player WILL be able to see your uploaded HD skin.
