What is the primary community/discussion server?

Looking around I find a lot of mailinglist related to Document Foundation and LibreOffice an different servers. Some of them seem to be gateways to Discours, but I’m not sure?

community .documentfoundation.org/

lists .documentfoundation.org/

lists .freedesktop.org/

It is hard to tell where the current activity is going on. I would like to ask for opening a mailinglist about “odfpy” (a Python package) project on a documentfoundation list server.
