Everyone can now contribute to translating the game into other languages, with an easy-to-use web interface here:
http://weblate.mightandfealty.com/You can register with Github, Facebook or via e-mail. You can see which parts of the game are translated into which languages how well, add translations or make suggestions for improvements and much more. You can translate a lot, or just a few lines, as you wish.
Take a few minutes out of your busy schedule and have a look.
