title: Remove categoies, tagging and authors functionality from wordpress
body: <p>How do you remove the tagging and authors functionality from wordpress.</p>
  
  <p>This is so it does not appear in the backend for users, it would remove the categories panel from the post page and all the other flim-flam.</p>
  
  <p>I would assume that wordpress's default post is a special kind of custom post type that can be modified, and therefore could have it's functionality disabled.</p>
  
  <p>Does anyone know how to do this?</p>
  
  <p>Thanks.</p>
