title: Is there a way to have a wordpress post category that is functional but not visible?
body: <p>I would like to display categories in posts and in post excepts, however I would alo like to use categories that help organise the display of posts around the site but are not visible.</p>
  <p>For example a 'featured' category that may be applied to a range of posts in unconnected categories, but that are the most valuable posts to show in a particular area. I don't want the category 'featured' to show to the user.</p>
