What if you have a new question or comment of your own? In a conventional lecture, you would raise your hand and, when recognized, speak to the class. The electronic equivalent, when you are reading a document in this website, is to create a new discussion thread attached to that document. To do this, click on the "New Discussion Thread" button at the bottom of the page. You will be taken to a page where you can create a new thread of your own.

If you like, go ahead and try opening up a new discussion thread targeted at this page.

Part of the art of asking good questions or of initiating a good discussion is to pick the right document. If the question or comment comes to mind because of something you are reading, the choice is obvious. If a question occurs to you at other times, however, give a little time and thought to the appropriate document. For example, if you have a question about a programming assignment, go to the page describing that assignment and ask it there. If you have a question about course policies and procedures, you should probably seek out the appropriate section of the course syllabus and attach your question there.
