Reminder. If you have not yet clicked the "Join Group" button and joined a special interest Group, you will only see the first post of each discussion there, not all the replies. And you'll not be able to post in the group. So do Join any group that interests you! (and just click "Unjoin" to easily undo that whenever you like.)
Forums, however, do not need to be 'joined' in order to see them and participate. The Forums here are a different thing than the Groups. The Groups are for more focused connections on specific subjects.
Do explore the different main links here, such as Photos, Videos, Groups, Forums, Members...
