        WebmasterWorld.com Refresh Message List / Reset Pointers Tweak
  ----------------------------------------------------------------------------

  Ever mark all messages read, then come back in a bit to see if there are new
  messages?  There's no link on screen to reload the page without marking all
  messages read again.  This tweak changes that.

  Ever find it jarring that the "reset pointers" link is on the left side
  of some pages, and the right of others?  This tweak changes that too.

  This Greasemonkey script is configurable.  There is a Config section in the
  code below.  Change either of the settings from true to false if you don't
  want that behavior.

  0.3  Expanded to category pages.  Added option to normalize reset
       link location.
