Here is a javascript function to bookmark any website:
Usage:

<script type="text/javascript">
function bookmark(url,title)
{
  if ((navigator.appName == "Microsoft Internet Explorer") && (parseInt(navigator.appVersion) >= 4))
  {
     window.external.AddFavorite(url,title);
  }
  else if (navigator.appName == "Netscape")
  {
    window.sidebar.addPanel(title,url,"");
  }
  else
  {
    alert("Press CTRL-D (Netscape) or CTRL-T (Opera) to bookmark");
  }
}
</script>

Hope this helps :)
