1. We offer one common forum for the 3 language versions of the website. The reason is that we want to bring forward the international exchange of knowledge and ideas.

2. We recommend using English as the main language of the forum, but contributions in French and German are welcome, too.

3. Anyone who wants to write in another language is invited to do so, but of course then there is a risk that this will not to be understood.

4. To avoid this, an automatic translation tool can be used. This will often produce grammatic mistakes, but for a general understanding it should be sufficient.

5. Thus we offer a link to the “google translator” here.

6. Our forum is an experiment in a mixed-language forum, with a focus on the English language. This requires a certain flexibility by the users, but it fits better into the present time and does not exclude anyone.
