A discussion has a title and heading that describe its purpose, and a series of messages posted by people who are responding and conversing. Discussions are not "chat-rooms," but they are more like organized electronic mail. You can browse a conference and post a message at any time. Someone else will see your post later, when they are browsing or when they check for new messages. All of the messages added to a discussion are kept until the whole discussion is deleted. You can always read the whole discussion from beginning to end, so you never have to wonder what people are talking about. If you click on the user's name or picture in a message, you'll get a short page of information about the user. You can send an e-mail directly to that person, or visit the user's home page if provided by that user. Scroll down if you need to, and click on the user picture (below). Click on the "OK" button in the user info page to return here. Because a discussion may have hundreds of messages posted to it, long discussions are split into smaller pieces. In a long discussion, you'll see buttons at the top and/or bottom that let you go back and forth, or you can just click on the "Recent Messages" button to see the most recent material. Click on the "Guided Tour" folder in the current path (above) to continue with the tour.
