I have just setup an account for Môssieur Ballon on Transifex and you can now translate any video tutorials' subtitles in your own language if you so desire.
To do so, you simply have to go to Môssieur Ballon subtitles translating project on Transifex.
Then click on the HELP TRANSLATE "Video Tutorials Subtitles" button.
You can easily log in with any of the following account: Google, Facebook, Twitter, Linkedin or Github. Or else simply create a Transifex account. The log in page will be in your own language.
