When first coming into Class Discussion, click on a Category title to see all the Topics under it. Click on a Topic to see all the messages posted there.

*Note: The first time you want to post on Class Discussion, you will be asked to set up a profile. This only consists of 3 short items, all optional. 1) a signature, if you desire one; 2) your location; and 3) setting your time zone. You will be able to edit your settings later in "My Settings", at the top of the Class Discussion page.
"My Signature" (optional) is anything you may want to appear at the bottom of each of your messages. For instance, your name, a short proverb or witty saying, etc.

You can Subscribe to receive new forum posts by email. Look for this feature at the bottom of your "My Settings" page, on every message you post, and at the bottom of every Class Discussion page. (You can later Unsubscribe from your "My Settings" page.)
