Hi again.

In functions.php, replace this huge thing:

  // get last reply time
  if ($postid) {
    $dateline=$DB_site->query_first("SELECT dateline
                                     FROM post
                                     WHERE postid='$postid'");
    $lastposttime=$DB_site->query_first("SELECT dateline
                                         FROM post
                                         WHERE threadid = '$threadid'
                                               AND dateline < $dateline[dateline]
                                               AND visible = 1
                                         ORDER BY dateline DESC
                                         LIMIT 1");
  } else {
    $lastposttime=$DB_site->query_first("SELECT dateline
                                         FROM post
                                         WHERE threadid='$threadid'
                                         ORDER BY dateline DESC
                                         LIMIT 1");
  }

  $useremails=$DB_site->query("SELECT user.*
                               FROM subscribethread,user
                               WHERE subscribethread.threadid='$threadid'
                                 AND subscribethread.userid=user.userid
                                 AND user.userid<>'$userid'
                                 AND user.lastactivity>'$lastposttime[dateline]'");

with just this:

  $useremails=$DB_site->query("SELECT user.*
                               FROM subscribethread,user
                               WHERE subscribethread.threadid='$threadid'
                                 AND subscribethread.userid=user.userid
                                 AND user.userid<>'$userid'");

that should be enough.
