Nakkid, your hack is still not correct.

+-----------------------------------------------+
| 1. Find this code:
+--------------------------------------------------------------------------+
if ($HTTP_POST_VARS['action']=="doupdate") {
+--------------------------------------------------------------------------+
|
+-----------------------------------------------+
| Replace it with:
+--------------------------------------------------------------------------+
if ($HTTP_POST_VARS['action']=="doupdate") {

  if (!in_array($bbuserinfo['userid'],array($caneditadmin)) and in_array($userid,array($caneditadmin))) {
    echo "<p>You are not allowed to edit this user</p>";
    exit;
  }
+--------------------------------------------------------------------------+

That means you (a) won't be able to edit ANY user, and (b) will not work if you have more than one user listed in $caneditadmin.
