I second Mr./Dr. Fahrner's motion to choose 12pt for BODY. Is
that the right thing to do? The only correction I found needed in
the Base Stylesheet is {font-family: Times, "Times New Roman"}, to
maintain the default font in Mac IE and NN.

My initial tests looked at a small part of the picture from
Macintoshes, and can make no conclusions except probably to not
set font-size [1]. I will try to be available to do more tests,
and can send a few real-world examples now if examples will help.

A new motion, re: CSS1 and CSS2 font-size:

  "..On a computer screen a scaling factor of 1.5 is
     suggested between adjacent indexes; if the 'medium'
     font is 10pt, the 'large' font could be 15pt." [2]

I move that the on-screen font scaling factor be changed from 1.5
to 1.2, and that the example size for 'medium' change from 10pt to
12pt.

I trust this is compatible with a 12pt sample/base style sheet, and
will help make text legible at 'medium' and 'small'; I am not sure,
even with these adjustments, that 'xx-small' can be used.

Corrections and comments are welcome.
