<title></title>
<script language="javascript" type="text/javascript">function addToBookMarks() {
bookmarkurl = "http://www.chandradev819.wordpress.com";
bookmarktitle = "Chandradev Blog";
if (document.all)window.external.AddFavorite(bookmarkurl, bookmarktitle);
else if (window.sidebar) window.sidebar.addPanel(bookmarktitle, bookmarkurl, ”);}
