Google's Christopher Semturs who works on localization and internationalization at Google posted in the Google Webmaster Help forums that they have a new forum category specifically to help on localization and internationalization webmaster issues.

Here you can find answers and ask questions on your multilingual and/or multi-regional websites. That means, it covers both translated content (e.g. both French and English for a website in Canada) and content for multiple regions (e.g. the same webstore selling content to Canada and USA). This is the right place to ask if your localized ranking does not work out well, for example if your USA-page ranks on top of your Canada-Page for users in Canada.
Internationalization is becoming more of an important topics for webmasters and developers to understand. As more and more web sites need to become localized, doing it right from a Googler crawler and a user perspective is critical.
This forum should help those looking to accomplish those tasks.
