The second copy of the "Zero Knowledge" article got posted because I used an off-line mailer (my old post being buried in my Eudora mailer archives which I had to search) and uploaded the article when I downloaded my mail, thus missing Matt Thomlinson's earlier posting of my article. Normally I read mail with "elm," for promptness and because I'm online reading News anyway. --Tim -- .......................................................................... Timothy C.
