Ok, I don't think it's legal to post any pictures of the kid's mesh, but after viewing the video from Phantom3d, I was very hopeful.  I had never seen the "necksmooy"  little adjustable line in Poser.

I managed to fix the arms and legs scaling using that method, it's fantastic.  However, I saw no actual parameters being changed in either the Joint Editor palette or the Parameters palette.  So my first question is, what exactly am I changing when I grab and stretch/compress that little line?  Is there anywhere I can see that parameter and adjust it manually?  When the joints are set up, is that an automatic joint parameter like twist/bend/side-side, or can I set up another one, like necksmooZ?

Why?  Because the neck was a different issue.  The neck in the toddler morph of the Kids is y-scaled down, not stretched out, and for some reason that's making the neck, in Poser (not Daz), squish out along the z-axis (didn't seem to affect the x-axis).  Nothing I did with the necksmooy joint (with or without falloff spheres) would correct that. 

Is there anywhere else I could look and adjust?  (hmm... perhaps I should duplicate this on a public figure and post?)  Is Antonia available to everyone?
