The conferencing system arranges text in a three-level hierarchy:
Anyone can post responses in a topic, or start new topics within a conference. Only the system administrator can create new conferences, though.
At the top of each page is a row of buttons. The first button, labeled [Next], is the one you use the most. Wherever you are, it takes you to the next topic or response that you haven't seen yet, from the conferences on your hotlist. Each user has their own hotlist, which is the list of conferences they are interested in. You can edit it via the [Settings] page, or add to it via the [All Confs] page.
See the Commands page for more info about all the buttons.
