@WolfgangFahl You would be surprised how quick the Dgraph team responds to threads, if you posted it here on Discuss. I felt the same way at first, and was hesitant to switch over to Discuss, but I was pleasantly surprised about how much more communication, and sharing there is here 
If you’re passionate about learning Dgraph and being apart of the community, it’s worth giving Discuss a try, and you’ll come to find out why it’s so great!
