Our website and forum is basically capable of handling multiple languages. At first, this only means that labels of functions and menus are automatically adapted to each language. For now only German and English.
Each author and user starts writing in a certain language. Technically no built-in mechanism exists to switch between languages for the content. It would be the responsibility of the writer (or ours) to create translations as separate versions or section within the article.
For some topics, like these notes on forum functions, we have created multiple versions in different languages from the start.
We will see how a forum with multiple languages will evolve.
