ArcGIS Blog The evolution of discussions Discussions, available to all ArcGIS Hub Premium customers, enable participants to post on maps or boards to capture feedback, generate ideas, and communicate without leaving Hub. We released private (group-only) discussions on content in 2022. Then we expanded to boards in 2024 for dedicated discussions. However, discussion channels have been limited in configuring who was allowed to participate and how, within groups, an organization, or the public.
