I attach my first working version of the german language files for the beta4 of UUB.threads. The Frontend is 99% done and the admin section 80%. There is some english text in it and I still working on it. The biggest part was replacing the placeholders in the frontend. Lots of changes.
I dont have installed the public beta yet so this languages files are untested but should give you a good start if you like to try it. I will release the next language pack if 7.3 reaches final and I'm able to install it within my modifications.
