This problem of getting 3 duplicate postings of all messages has happened twice to me in the past and went on for several weeks. After extensive correspondence with Barb and Janet, the only solution was to unsubscribe from the list and resubscribe. At one time I couldn't post anything because listserver no longer recognized my e-mail address (there had been an invisible change here at the company). In that case Barbara had to manually unsubscribe me and then I re joined. Darwin
