No problem, Larry. I've unsubscribed you to the main list. But would you be interested in getting the digest instead? (Just one message a day - this is how I read both the ASTRO and SEESAT-L lists, for instance.) Let me know, as your contributions to the list have definitely been valuable! If not, check back in with us in the future: like any other mailing list, we're constantly changing. Clear skies, Lew
