hi there,
if you'd like to help out with translating then you're welcome to do so.
we're using transifex and you can register there and apply to join the team.

if you'd like to have some more details first or if transifex is a grey area then I would say to Google a bit, send Ernst a pm or post a message here in the forum.
be aware that the en-us language is being modified by developers at the Github repository but if you can help out with any other language then that's great.
