      <h3>Nodes</h3>
      <p>The core of the Drupal system is the node. All of the contents of the system are placed in nodes, or extensions of nodes.
      A base node contains:<dl>
      <dt>A Title</dt><dd>Up to 128 characters of text that titles the node.</dd>
      <dt>A Teaser</dt><dd>A small block of text that is meant to get you interested in the rest of node. Drupal will automatically pull a small amount of the body of the node to make the teaser (To configure how long the teaser will be <a href=\"%teaser\">click here</a>). The teaser can be changed if you don't like what Drupal grabs.</dd>
      <dt>The Body</dt><dd>The main text that comprises your content.</dd>
      <dt>A Type</dt><dd>What kind of node is this? Blog, book, forum, comment, unextended, etc.</dd>
21
      <dt>An Author</dt><dd>The author's name. It will either be \"anonymous\" or a valid user. You <em>cannot</em> set it to an arbitrary value.</dd>

      <dt>Static on front page</dt><dd>The front page is configured to show the teasers from only a few of the total nodes you have on your site (To configure how many teasers <a href=\"%teaser\">click here</a>), but if you think a node is important enough that you want it to stay on the front page enable this.</dd>
      <dt>Allow user comments</dt><dd>A node can have comments. These comments can be written by other users (Read-write), or only by admins (Read-only).</dd>
      <dt>Revisions</dt><dd>Drupal has a revision system so that you can \"roll back\" to an older version of a post if the new version is not what you want.</dd>
      <dt>Promote to front page</dt><dd>To get people to look at the new stuff on your site you can choose to move it to the front page.</dd>
      <dt>In moderation queue</dt><dd>Drupal has a moderation system. If it is active, a node is in one of three states: approved and published, approved and unpublished, and awaiting approval. If you are moderating a node it should be in the moderation queue.</dd>
      <dt>Votes</dt><dd>If you are moderating a node this counts how many votes the node has gotten. Once a node gets a certain number of vote it will either be approved or dropped.
      <dt>Score</dt><dd>The score of the node is gotten by the votes it is given.</dd>
      <dt>Users</dt><dd>The list of users who have voted on a moderated node.</dd>
      <dt>Published</dt><dd>When using Drupal's moderation system a node remains unpublished -- unavaliable to non-moderators -- until it is marked Published.</dd></dl>
