I've opened up a new skin repository at http://www.makehumancommunity.org/skins.html now. There you can find the annotated skin which has been discussed elsewhere.
There is also a FAQ on skin construction at http://www.makehumancommunity.org/wiki/ ... extures%3F as well as a new turorial on texture painting at http://www.makehumancommunity.org/wiki/ ... in_blender
