The teaser can be changed if you don't like what Drupal grabs</li><li>The Body - This is it, the heart of the matter. Your text, what we want to read.</li><li>A Type - What kind of node is this? Blog, book, forum, comment, unextended, etc.</li><li>An Author - The author's name. It will either be \"anonymous\" or a valid user. You <i>cannot</i> set it to an arbitrary value.</li>";

These comments can be written by other users (Read-write), or only by admins (Read-only).</li>";

So promote it too the front page.</li>";
  $output .= "<li>Moderation Status - 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 Approved and Published, Approved and UnPublished, and Awaiting Approval.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 <b>not</b> moderating a node it should be Approved</li><li>votes - If you are moderating a node this counts how many votes the node has gotten. Once a node gets a certain number of vote if will either be Approved, or Dropped (To setup the number of votes needed and the promote and dump scores ". l("click here","admin/system/modules/queue") .".)</a>.</li><li>score - The score of the node is gotten by the votes it is given.</li>";
