That should be available in Settings -> Groups
nodebb groups on steroids
One of the things im starting to like on nodebb is the ability to create groups and have a little something for them like the header and users posts.
If everything is over modules, why its not on widgets? I would love to have change some stuff on the fly like on custom pages plugin.
Ex: show a particular category posts for that group.. show a possible calendar (this plugin this works?!) and so on...
