It was just pointed out to me that google offers more than just the standard languages. Here are a few selections of other languages:

• Hacker

Unfortunately, most of those of the above that are cited as “100%” complete here are not complete. The Hacker version of the About Us pages is complete, it seems, but the others are not.
