Here yee go:
http://www.javascriptkit.com/script/...destatus.shtml
but put the URL you want to display in
var statusmsg=""
EDIT - Shit, I'm assuming you can't modify the links themselves at all...
So try this one -
http://www.inetmarketing.com/seminar...status_bar.htm
No toying with individual links at all - and again put your URL of choice in
window.status=''
