This  is very interesting.  I'm on ES, I tested it and
it  works  indeed.  I  also  found  that my ISP's news

The  situations in which canceling a message is useful
are  rare;  typically once in several months.  So it's
not a problem if it takes a little more effort.

this and all those other ES newsgroups.
Thanks a lot!
