Thanks.

I did what Glenn suggested for the mailing list changes.  One concern:
my reading of the "Topics" page is that the topic matcher scans the
_body_ of the message, so the suggestion to use "Keywords:
emacs-announce" in the _headers_ of the mail will probably not work.
Or maybe I misunderstood what Glenn meant by that.

I did nothing about item 4 in Glenn's message.
