Transition to Discourse
I believe that I speak for most people when I state that this forum software is noticeably more basic than Discourse's. In fact, if you monitor the engagement metrics at the organizations which provide multiple forum technologies, it's even visible that more flock to their Discourse instances.
I believe that TeamViewer should (ideally) completely transition to Discourse for their forum, or at least provide an instance themselves and advertise it in this forum, to ascertain demand for a superior forum.
Otherwise, people shall surely just move to Reddit. I know that this post would gain more traction there.
