<<Another observation: Both this time and last, I only saw the repeats
in this group, of the half-dozen or so that I read regularly>>
Can't explain that. This is happening all over the place. I have observed
it in at least 7 or 8 newsgroups. This has happened before but I think the
last time it occured the posting dates remained unchanged so it was easy to
tell which messages were new and which were re-runs. This time all the old
messages have today's date.
