I have been reviewing some posts in the tdwg-content archives and got to this one: http://lists.tdwg.org/pipermail/tdwg-content/2010-August/000060.html It references a number of previous posts related to background on the DwC standard, such as http://lists.tdwg.org/pipermail/tdwg-content/2009-June/000019.html However, those links don't seem to do anything any more. There are other emails whose URLs begin with http://lists.tdwg.org/pipermail/tdwg-content/2009-June/ found in the June 2009 archives: http://lists.tdwg.org/pipermail/tdwg-content/2009-June/thread.html but not the ones referenced in the August 2010 message. I have been assuming that although it is a bit inconvenient to look things up in the list archives, the messages that have been sent would nevertheless be permanently archived. Is that not true?
