unfortunately there is a problem on the part of our Internet provider which has not yet been solved: subscribers to the English-language newsletter receive the German version by mail. We are very sorry about this! However, you still have access to the English version. Please click on the button „READ MORE“ in the newsletter you receive by mail. You will then be directed to the corresponding entry on the GERMAN homepage. Now click on the Union Jack (= the flag of the United Kingdom) in the top right window and you will be redirected to the ENGLISH version of the page.
We sincerely hope that the problem will be solved soon. Stay tuned to us!
