You may wish to avoid sending emails to the author of the change, if the author is subscribed. Because- of course the author already knows that he/she made a change. I submit the below code change in order to work around this issue. It may be desirable to add a config flag for this setting. Possibly something each individual user can toggle for him/herself. At this point, it is on for everyone. ~Sherri W (www.start.ofitall.com).

In Detritus (& possibly older?) a change is needed to 'function notify()' in inc/common.php, to set 'self' to 'true':

• Edit the inc/common.php file.
• At the end of this file is a function called subscriber_addresslist(…). This function gets the list of subscribers to a page. This function should now have a new parameter ($exclude_current_user). And it checks if the given user is the current user in the foreach loop and skips it. Replace your version with this new version:

/**
 * Return a string with the email addresses of all the
 * users subscribed to a page
 *
 * @param  string     $id					  Page id.
 * @param  boolean    $exclude_current_user   Indicates whether to skip the currently logged in user. To prevent email of your OWN changes to you.
 * 
 * @author Steven Danz <steven-danz@kc.rr.com>
 * @author (Workaround to skip current user) Sherri Wheeler (www.start.ofitall.com)
 */
function subscriber_addresslist($id, $exclude_current_user=false){
  global $conf;
  global $auth;
  global $USERINFO;

  $emails = '';

  if (!$conf['subscribers']) return;

  $mlist = array();
  $file=metaFN($id,'.mlist');
  if (@file_exists($file)) {
    $mlist = file($file);
  }
  foreach ($mlist as $who) {
    $who = rtrim($who);
    $info = $auth->getUserData($who);
    $level = auth_aclcheck($id,$who,$info['grps']);

    if(  $exclude_current_user && ($info['mail'] == $USERINFO['mail'])  ){	    
      continue;
    }

    if ($level >= AUTH_READ) {
      if (strcasecmp($info['mail'],$conf['notify']) != 0) {
        if (empty($emails)) {
          $emails = $info['mail'];
        } else {
          $emails = "$emails,".$info['mail'];
        }
      }
    }
  }

  return $emails;
}

• Finally, in the same file, the notify(…) function makes a call to the subscriber_addresslist function (around line 841). Change this to the following:

...
$bcc  = subscriber_addresslist($id, true);	// Exclude current user (author of the changes).
...

• That's it! It may be helpful to, instead of hard-coding the 'true' value into the call to subscriber_addresslist (…), to rather make that into a config variable.
