I am totally confused. Is this community mixed language or EN only and some dudes, me include sometimes, post in his own language.
Should be create language areas? FR, DE, IT, CN ans so on…
Most topics are in English. Some are french, some German (as Skymatic is located in Germany).
Writing a message in English has the advantage of making it easier for many international users to understand and perhaps find an answer to their questions.
Since not all users speak English, questions in other language usually are also be answered.
So no, there’s no „official“ language given in this board.
And is more polite.
