On another subject, I just upgraded to Netscape 4. something and have
discovered it is no longer simple to respond privately to a message sent via
the list.  So now I join those who keep saying how tough this is (yeah, I know
Mark, quit fooling around with Netscape and use Microsoft).  I will figure out
a way around this program.
 
See ya,
