I have to be honest and say that I think it is highly unlikely you can guarantee the cancel in the distrbuted environment of the Internet. And that is what will be required. I even think you would be hard pressed to prove that the nntp CANCEL is 100% effective. By that I mean that no one at any site had read a message that was also cancelled. john noerenberg jwn2@qualcomm.com -------------------------------------------------------------------- "We need not to be left alone.
