What is a subdiscussion?
A subdiscussion is a subdividion of the discussion. The forum that you are visiting may cover such a broad topic that it has been divided into multiple discussions with each discussion broken down further into subdiscussions. For example, a discussion on Mathematica may be broken down into subdiscussions based on the platform (Windows, Macintosh, Unix, etc.) on which Mathematica is run. You can choose the discussion or subdiscussion that is right for you directly on the main discussion listing screen. If you are already in a discussion screen and it has subdiscussions, you can also go to any one of them by clicking "View Subdiscussions" at the top right of the current discussion topic listing table or by selecting it at the bottom of the topic listing table.
What is a topic?
