Do you just want to remove it?
If so you would remove the <hr> found here
Code:
<div id = mail>
<hr>
<p align="center"><font size="+1" face="Monotype Corsiva"><a href="javascript:bookmarksite('GTFalconpics.com', 'http://www.gtfalconpics.com')">Bookmark
Us!</a></font></p>
<p align="center">Template designed by <a href="javascript: void(0)" onClick="MM_openBrWindow('http://athene.riv.csu.edu.au/%7Epfranc02/','BigPETEdesigns','location=yes,status=yes,menubar=yes,scrollbars=yes,width=1024,height=768')">bigPETEdesigns</a></p>
</div>
</div>
and thus:
Code:
<div id = mail>
<p align="center"><font size="+1" face="Monotype Corsiva"><a href="javascript:bookmarksite('GTFalconpics.com', 'http://www.gtfalconpics.com')">Bookmark
Us!</a></font></p>

</div>
