//  Prosper Listing Forum Thread Finder script
//
//  Purpose:
//  --------
//      This script fires on a Prosper.com listing page to insert
//      hyperlinks to any forum threads that link back to the listing.
//
//      These threads are found by Friedo's spider and (soon) by
//      ProsperMonkey.
//
//      See: http://forums.prosper.com/index.php?showtopic=20911
//      and http://prospers.org/wiki/user_ProsperMonkey
//      for more information.
//
//      Note that this is the ajax version that pulls requests from
//      up to two sites besides Prosper.com
