Since all of the above web pages are in German, here's a language translator web site:
http://babelfish.altavista.com/When you open an above link, highlight the entire address located in the address box near the top of the window by right clicking anywhere in the box. When the little menu appears, click 'copy'.
Now open the translator web page and locate the box toward the bottom of the page right underneath the 'Translate a Web Page' text. In the box you will see 'http://', delete that out. Now right click in that box that is now empty and when the little menu appears, click 'paste'. The web address will appear in the box.
Next, select the languages translating from and to in the drop down box located directly under the address window you just pasted to.
When you've done that. click on translate, and wait for the page to appear. It won't be a complete translation, but you'll get an idea of what the page says. This is what I did to come to the above conclusions.
I hope this helps!
