At this point it's moot since Ken said he resizes in TIFF and sharpens, but
I think you are correct - conversion from TIFF to JPG reduces file size and
apparently compresses, I would think to Maximum quality.  Sharpening at that
point was what I was suggesting, before saving as a more-compressed JPG.

Alas, either I am misunderstanding you or I am terribly confused; both
options are entirely possible.
>I would convert and sharpen before compressing
If you convert any file format to a JPG format, are you not coverting and
compressing at the same time?  I did not think that in fact they are
practically separate and distinct operations even if the act of coverting
presents itself to the user as if it were being done in stages.  Thus, if I
am correct about the conversion and compression processes being from the
users point of view for all intents and purposes one in the same, how does
one sharpen between the conversion stage and the compression stage?
