When a Forums conference first opens, you should see all the forums you can participate in. See Setting Your Options for detailed information about each option you can set. In a conference that consists of many forums, each of which consists of dozens of threads, the list of threads may be very long. To help you see what forums are available in a conference, you can collapse the list of threads in a forum in the main conference page. In the main conference page click the arrow button next to the forum name.
Forums hides the list of threads in the forum.
Click the arrow button again to expand the list of threads in the forum.
