I suggest using your first or last name and the same password as you use for e-mail. Follow the directions. You need only give the required information. Once you are registered as a user, you will see the conference screen. On the right, you can read the actual messages.
Conferences have topics and topics have messages.
You will see a conference labelled IS243. The most common way to make a posting is to reply to a message that is already there. I will post questions and you do the assignment by replying to my message. Please do respond to the messages of other students, also. This is important for several of the set assignments.
