CONGRATULATIONS!  Finally, someone is paying attention!

I wrote this series wrong in the first place just to see if anyone
is reading these postings, hence the smileys ;) ;) ;) at the end
(omitted above).  But if you continue reading the digests you will
see that later (digest 1358) I pointed to the error (I did not
mention that it was intentional thinking that it was obvious) and
Greg used it as another argument for using a light meter vs. mental
calculations (as if one cannot screw up with a light meter...)
