Thanks for responding.. didn't think i would get anyones attention. yes i do have the model and skin already done.... i've attached a picture, so hopefully you can see what i'm doing. The reason why i want to animate and attach the head after all the body animation is done first, is because i want to be able to concentrate on the facial animation without it moving because it's connected to the body. Well take a look and give me your opinion.
(The reason why i would want to do it this way, is because i think i saw something similiar to in last years siggraph(2002) or something behind the scene movie)

Thanks again
