From: Rich Alderson
it is impossible to respond privately unless you
happen to have a bunch
of old messages archived and the person to whom you want to respond is
someone who has written previously.
If you go into the list archive:
http://www.classiccmp.org/pipermail/cctalk/
the email address of the sender, for any given message, is still listed (in
slightly mogrified form).
