This code only writes the link if IE browser:
<SCRIPT language=JavaScript>
<!--
var agt=navigator.userAgent.toLowerCase();
var is_aol = (agt.indexOf("aol") != -1);
if (navigator.appName=='Microsoft Internet Explorer' &&
is_aol==false) {
document.write('Don\'t forget to print this page and to <A
href="javascript:AddBookmark()">bookmark</A>
this site.');
}
else if (navigator.appName=='Netscape') {
document.write('Don\'t forget to print this page.')
}
else {
document.write('Don\'t forget to print this page.')
}
//-->
</SCRIPT>
This code goes in the head.
<SCRIPT language=JavaScript>
<!--
var url = "http://www.digitalwidgets.com"
var name = "Digital Widgets"
function AddBookmark() {
window.external.AddFavorite(url, name)
}
//-->
