I read in one of the e-mails sent to the Mailing List that Richard Schawrtz donated an invention r something to the list. I've benn e-mailing quite a while, and he never mentioned anything about. I can't find his e-mail. Does anyone know about this? ---------------------------------------- Asaf Shtull-Trauring, Amateur Astronomer http://www.maxnm.com/asaf/
