Jenstar: “If you are wanting an AdCenter account, yet haven’t received an invite yet, they are having a three hour open call period today where you will be guaranteed a shiny new account.”

MSN adCenter does not currently support the web browser you are using. Please sign in using Internet Explorer 6.
I shouldn’t complain, I think. You want Microsoft ads? Better use IE. Oh well, I think I’ll keep my AdSense ads for now.
Opera will let you do it.
BTW.. it wasn’t for putting ads on your site, it was for becoming an advertiser with them.
