@ odf,

The jaws and tongue might be other actors that people might sometimes want to translate, also the hands if IK chains get added. Personally I don't get the point of forcing translation limits to zero for any actor. I all my time using Poser I have only ever once seen it cause a problem, and I'm not aware of any other figures that use limits that way. Perhaps there is a point, but it is beyond me. I don't suppose it will do any harm so long as the actors mentioned above can be translated.
