Your instructor can add e-mail capability to your course. The bulletin board can be used to post messages for others to read or respond to, usually at a different time, often called threaded discussions. In WebCT, you can also text chat through the bulletin board with other people if you are both online at the same time. It allows two or more people to communicate by shared signals of starting and stopping. Real-time communication between course participants using a graphical paint interface.
Participants can draw on the whiteboard and other course participants can see what has been drawn.
