You're welcome to post in whatever language you like. Your native language would be preferable to a Google translation. Others can use Google translate to read it, if they choose. That way, the intended meaning of your post will not be lost in the translation. (Sorry, but "Please make the achievement of German users!" makes no sense.)
If you really want a separate forum for German users, you would have to convince nostra it's viable and would not require his limited time and resources. I assume he would participate in a German forum, but you wouldn't get any help from those of us who don't understand German. You could post a poll to gauge the level of interest and support for a German forum.
