Yammer has gone global. People in more than 130 countries have joined their company networks, and we want to make sure everyone, everywhere can use Yammer to help their teams get things done. We’re thrilled to introduce our new Translations application, which will give our users the power to translate our site into 94 (and counting!) languages. They’ve already translated the site into French, Dutch, German, Korean, and Spanish, and Japanese, Portuguese, Swedish and Turkish aren’t far behind.
Want to get involved? It’s simple: click the “Start Translating” link at the bottom of the page to apply to become a translator. Translators can right-click on text in the Yammer interface to translate it in place. Each translator can submit or vote on translations, and the highest-rated translations become the text of Yammer’s interface in each language. The best translators will win their places at the top of our translator leader boards, complete with coveted virtual badges.
Users who would like to use the site in a new language but don’t wish to be translators can click on the “English (US)” link (also at the bottom of the page) to choose from a list of available languages.
We’d like to thank all the users who have already helped us make Yammer a better product for everyone to use. With your continued help, we’ll add support for additional languages, and as they’re translated, we’ll let you know!

Seems to be a very good idea. Everybody working on your program doing translation services and now you have 94 different languages available. Great work.
Thank you!
