There have been a couple of people reporting that they have had postings returned as duplicates (even though they were not). I have had the same...but I also got replies from poeple who had read them so I did not repost. This must be a bug in software changes made to protect from spam, etc.. System admin people, please be aware of this problem of bouncing messages as already posted when they are not. Thanks. Mark A.
