Sorry about the multiple deliveries! My mailer reported that delivery had failed and would be tried again during a later check of mail. While waiting, I added a few comments here and there, as I didn't think the earlier versions had gone out. Apparently my mailer lied to me. Sorry. --Tim May "Aren't cats Libertarian?
