Apologies to RSS feed subscribers who experienced feed overload this afternoon.  We were working to shift the new feed to old subscribers without necessitating a new url.  I’m told that we were successful, but not before subscribers received multiple versions of the same postings in their readers.  The problem should be solved, but note that the new site has a wider selection of more stable feeds that may make switching worthwhile.  The full list is on the RSS Feed page.
