Just to note, while our site is in it’s beta version at the moment, posts in the particular group are still appearing in the main site’s public “Feed”. However, as the site’s content grows, the ready to launch feature “Relevant to me” will be turned on and then every user will only see the “Feed” that is completely personalized, per YOUR specification – by default private.

NOTE: However, any and all posts and comments within the groups that are already set to “Private“, will be only visible to the members of such groups and ONLY THEN they will appear in the site’s main “feed” and ONLY if your are logged on.
