Each module and topic begins with a brief overview. Then, at your own pace, explore the material provided. Topics might include a short 'streamed' video component along with written material and images. At the end of each topic, on the bottom of the page, is the discussion area. The discussion area works very simply.
New messages appear at the left margin.
Responses appear indented below it. You can read every message by clicking on the next button. For more detailed instructions, click on the help button on the bottom of the discussion area page. Another form of help is the glossary. Words that are unfamiliar to you are cross-referenced to the glossary.
