Sparkle Skye

I am using the standard size scene in maya and n the layers I see a layer called Avatar_Weights_source. I am not sure what this layer is for since I have read you can not rig to that but need to use the other skeleton layer. What I was wanting to do, was set up some poses to test my weighting on the medium size, however that avatar is not weighted. Is there a way to do this? I tried selecting the avatar weights source and copying skinweights but it give me this error -- Must select a source and destination skin or component on a source and destination skin.

wow this is intriguing
