Would be nice to have a group board
You can do this manually, just create a category for that group and only allow that group to find/access/post in that category.
But it wont show on group page like some special thing 😜
I think it would be great to link a group to a category because that qay group page could show some great info about that category like active threads, top poster of the group or last threads.
Nowadays it show all people post wich is not relevant at all
