have you created an account on Transifex?, I think we need @lah7 to confirm if it is still active!.
Don't waste too much time unless you can log in and actually change things that need changing!.
If you like, you can also help out in the German section of the forum, I am working on an installation guide in German which also needs to be be proof read and edited!. (You can only edit a Wiki if you have been on the forum a while and have made several posts/threads!):
