Administrators can add primary and secondary news channels to Universe.
Primary news channel
The primary news channel is added and displayed automatically to all users, however they are not automatically participants of this channel. Primary news channel has by default notification settings set to high, which means that all users added to this channel (or joined through discovery) will receive email notifications from new posts.
Primary news channel discovery option needs to be set to "Anyone can join" in order to work.
Secondary news channels
Secondary news channels can be any channels. They are shared to users as any other channel. If user is member of secondary news channel, that channel will be added to the news feed on users right side of My Feed -page.
All secondary channels are also forced to be non-muted and non-hidden so users will see these channels in their channel navigation.
