Larry,

        Thanks for the link, I'll read it as soon as I get done with my E-Mail. 
Can O2k be set so that it doesn't auto download images?  if so where does
one go to change the setting?

        Ok, what about their "self-destructing" E-Mail, E-Mail that the sender can
"revoke," preventing the recipient from either printing or forwarding an
E-Mail?  How do they do those things???

Herman
Live Long and Prosper
