test post

I apologize for the bandwidth waste, but I have sent four posts to the list this week from my usual posting site and none of them have appeared. Ironically, the first two (the second one was a re-typing of the first) discussed the unreliability of email and its implications for mailing digital cash. I also sent a 13K byte message describing how Cah\\ Chaum arranged to detect double-spenders of digital cash. If this message appears I'll try re-sending some of the others. Is anyone else having posting problems? Hal hal@alumni.caltech.edu
