insert your html right before:
</td></tr><tr valign='top' align='left'><td class='head'>Password<br />(type a new password twice to change it)</td>
you may want to add a:
</br>
before your html
</br>your html here</td></tr><tr valign='top' align='left'><td class='head'>Password<br />(type a new password twice to change it)</td>
it's an ugly section, you may want to do a find on the whole string
