When I set the "Preferred language" here in this board to German (I didn't test the other languages), the board is broken: Many strings get just empty and I get a huge warning at the bottom about a missing copyright text. I can't even change it back since the two topmost entries in the "Modify Profile" menu disappear - I had to digg up the URL from my browser history to change it back.  So please either fix the strings (filling with English default texts would already be much better than the current state I couldn't see any German text anyway) or prevent people from unexpectedly breaking their account. I already thought something on my end didn't work properly.
