Most folk probably don't know that the first Mail User Agent (MUA) which 
enabled manipulating individual emails, was written by Larry Roberts, 
while at ARPA, as a set of TECO macros.  (Steve can elaborate, including 
on his own role for that.)

A reimplementation and enhancement effort produced John Vittal's MSG, 
which became widely popular.  It was also the first occurrence of 
forwarding and replying commands.
