Hi LILY1914 -- my apologies for not seeing your question sooner! This is an issue that confuses many people, particularly newer members -- unfortunately, because of the way Spark People is set up only 3 thread titles show under each forum name, except for the first one, which shows 5 threads. If you click on either the name of the forum or on the "see more topics" button, however, a much longer list of threads will show up (and may even include additional pages that you can go to. The threads that say "sticky" will always stay at the top of the list (unless the sticky feature is removed by a team leader); otherwise, threads with the most recent posts move to the top.
I hope this will help not only you, but other members as well !
