When you click a Spoofed link, look at the very top of the IE Window. You know, where it says 'Site Name - Microsoft Internet Explorer'.
Well, as it's loading the page and before it's loaded the Page Name, the URL appears and (On IE6 SP1 which is what I'm using) a small square appears right after the URL.
I know it's not much of a help, and maybe a tad hard for people on Broadband to notice, but it's a help all the same...
