Moreover, many countries may have their own local boards, can every member post there or is there any obligation to follow in this regard?
Post only in your local board. If you are from Indonesia, what's the essence of posting in German board?

In fact, if you're caught doing machine translations you could end up being banned for breaking the rule nr. 27.

But if you write in your own local, that's a great start. It will be easier for you to learn the fundamentals, because it's always easier to internalize knowledge in one's mother tongue; there are several merit sources in locals who will help you rank up if you deserve it; and although I can't find where right now, theymos himself recommended newbies to start there somewhere. So, if that's the case for you, take advantage of it!
