Since the SVN only has a dozen languages in there, I’ve built a list of over 50 languages I have found over the years that bbPress internals have been translated into.

Some are more complete than others (people made a half hearted attempt and gave up, ie. on the backend). But some languages are hard to find so it’s handy to have a starting place and then you can fix them up with poedit.
