Read the Poser Tutorial PDF.  Not the Poser Manual PDF.  Learn first about the zero pose and about turning IK off for the legs.  Learn about the file extensions used and the reasoning behind why things are stored in the Poser Library the way they are.

Then explain what the Runtime folder means.  Maybe why it's even called Runtime, because for years I just assumed that it contained EXE files in it.

I recently started learning Poser hardcore (about three weeks ago).  Now I know how to model my own Poser figures from scratch (except for use in the Face Room).
