It took only 20 days to tap in all the areas mentioned on this short-term roadmap. 
The Community Wishlist process is working. Next is to clarify whether and how the Bitwig team wants to use it.
The collaboration with Bitwiggers has also entered a stable phase, after connecting +2600 presets and clips with Bitwish topics. Next is to see whether presets creators and users find this space useful.
The Bitwig Video Guide (maybe we should simply call this section “Tutorials”) is also stabilized, after all the expected topics have been created. Next is to proof whether tutorials creators and users find this space useful.
The Music section has started with a monthly topic and it seems to be catching up. Next is to see whether this becomes a space whether music creators can receive feedback and make connections.
The Bitwish badges are a reality now, and dozens of Bitwishers have got theirs already. Suggestions for new badges are welcome.
About the private groups, this is Discourse functionality that comes out of the box. Currently they are not being promoted because we seem to need a critical mass of individuals first. In any case, if you want to try a private group for any Bitwig cause, just request it.
