That's what you see if you live outside the USA and try to sign up to "Join the Social" and get your Zune Tag. I can understand (though not agree with) the reasons why Microsoft isn't yet selling the Zune outside the USA (music licensing issues), but come on: there's no reason why people outside the USA can't sign up for a Zune Tag and join in the fun. Microsoft is really being harsh about this while "only for Americans" thing.
Thankfully, there's a fairly easy way around this: go to Passport.com, create a new LiveID, and say that you live in the USA. That's all you need to do in order to get a Zune Tag (that's how I got my Zune Tag) - but, sadly, it won't be linked to your real LiveID so there will be some disconnect there.
