The I.am-KingPin Skin Registry is now up and running. The way Kingpin handles custom multiplayer skins is to use a unique 3-digit number for each one of each model's three body parts (head, body, and legs), so there can only be 1000 skins. "The registry will ensure that everyone who makes a new skin and submits it to I.am/Kingpin for download uses a different number."
