Though each post on your site is a node, each post is also of a particular <a href="@content-type">content type</a>. <a href="@content-type">Content types</a> are used to define the characteristics of a post, including the title and description of the fields displayed on its add and edit pages. Each content type may have different default settings for <em>Publishing options</em> and other workflow controls. By default, the two content types in a standard Drupal installation are <em>Page</em> and <em>Story</em>. Use the <a href="@content-type">content types page</a> to add new or edit existing content types. Additional content types also become available as you enable additional core, contributed and custom modules.
