I'm not sure that Forza is International and really it's not availible in most general book/magazine stores, it might be availible by subscription only. I'll have to get the address for you Mon. so that if you're interested you can get a subscripsion.
You should be able to find Forza over seas. I live in Japan and can also find it. The unfortunately don't have a website. However, check www.forzamagazine.com It points to a site with a listing of every issue. Email the guy he may know where to get it.
