Good point, I had in on my to do list to give an update here.
Due to a re-prioritisation of our tasks, we have to postpone the change a bit. The migration of the old posts to the new platform turned out to be more complicated than we expected, so we need a bit more time to do this.
So we still plan to move to our own hosted community site, but we are busy working on the core platform.
We will update here once we are ready.
Thanks to all active community members for contributing here!
