This German language sub-forum looks at the moment as if it is only intended for archiving posts from the Duolingo forum.
But as I understand it, there is just as much possibility to ask one's specific questions or share one's experiences here as there was back in the Duolingo forum.
Not that it is misunderstood, my thread here is not meant for you to ask all questions here in this thread, but to open your own original post in the forum so that other learners or native German speakers can reply there.
