Community site lacks Navigational and Back links

Where is there training on using this system?  I find it pretty useless to drill into a Discussion Group, Reply to a user post, and then there is no way for me to click back out to the primary community.  I have to keep resorting to browser bookmarks or an email that has the new link.

 

My main concern is the Fortify area, but I have seen it on the old WebInspect forums as well.  Shouldn't there be a navigation tree or series at the top so I can go "back up" the proverbial subject tree?
