Posts in discussions now identified as "NEW" if posts were added since user's last visit to resource or bulletin board.  "Speech bubbles" in NAVMAP also displayed for each resource or bulletin board if posts have been added since last visit.

User can set display to be all posts, or only unread posts.  To support cases where there are several "NEW" posts, the time of the previous visit is passed in a query string during hide/make visible, reply or delete operations so that the differentiation of "NEW" posts is retained until the user leaves the bulletin board.  This behavior does not currently apply to discussions associated with resources.
