allright, i created a box, gave it a finish{ reflection 1 } and pointed a
spotlight at it.  but when i traced it, even in MEGE POV, thers no light
reflecting off the box onto the plane the box is sitting on.  it reflects
everything else, but the area which is supposto be lighted with reflected
light is still dark.

If you are in fact using MegaPov then you need to enable photons for
the reflecting object. You will need to also specify "reflection_on"
in combination with the photon mapping feature.

Well, reflection on, without the underscore, to be exact.  Unless I've missed out on a
change.
Furthermore you need the keyword  target  in the photon block of the reflective object
you want the light to
bounce off of.  At least in my knowledge that is the case.
The HTML (or other form) help file for MegaPOV is a great resource anyhow.

More exactly:

global_settings { photons { count 10000 } } // or higher
...
box
{ whatever
  photons { target reflection on }
}
