Hello world, we have two news.
First one will benefit non-English speaker members, the International Simutrans Forum is back with multi-language interface. You can choose one from a list of 11 available languages for the forum interface: Czech, German, Spanish, French, Italian, Dutch, Portuguese, Russian, Swedish, Chinese and Japanese. To set your preferred language, go to your Profile > Modify Profile > Account Related Settings > Preferred Language.
Secondly, our Simutrans Wiki Manual has now a French Wiki, which will be replacing the old French wiki from Old Wiki. You can help transferring the documentation from old wiki to the new one.
