  $output .= "<p>The comment module enables users to submit posts that are directly associated with a piece of content.  These associated posts are called <i>comments</i>.  Comments may be <i>threaded</i>, which means that Drupal keeps track of multiple subconversations around a piece of content.  Threading helps to keep the comment conversation more organized.  Users are presented with several ways to view the comment conversation, and if desired, users may easily choose a <i>flat</i> presentation of comments instead of threaded.  Further, users may choose to order their comments view by <i>newest first</i> or by <i>oldest first</i>.  Finally, users may view a folded list or an expanded list of comments.  Folded limits the comment display to <i>subject</i> only.  Drupal remembers the comment view preference of each user whenever he changes a view setting.</p>";
  $output .= "<p>Since a busy site generates lots of comments, Drupal takes care to present a personalized view of comments for each user.  The home page lists displays the number of read and unread comments for a given post for the current user.  Also, the tracker module (when installed) displays all recent comments on the site.  Finally, comments which the user has not yet read are highlighted with a red star (this graphic may depend on the current theme).</p>";

  $output .= "<p>Comments behave like other user submissions in Drupal.  Specifically, ".la("filters", array("mod" => "system", "type" => "filter"))." like smileys and HTML work fine if the administrator has enabled them.  Also, throttles are usually enabled to prevent a single user from spamming the web site with too many comments in a short period of time.</p>";
  $output .= "<p>Administrators may control which persons are allowed to submit and administer comments.  These controls appear in the ".la("user permissions", array("mod" => "user", "op" => "permission"))." administration page.  Additionally, administrators may edit or search through comments on the ".la("comments admininistration page", array("mod" => "comment")).", as well as set the default display view for new users.</p>";
