A note to the list...

I don't like to see conversations squelched before they're over.  If you're
tired of the thread, stop reading it, and don't respond!  We're all pretty
familiar with the subject line by now so they're not hard to delete.

Yes, we've been over this ground before (a few too many times for my taste), but
if people want to keep bantering, they should be able to.
