The way you will communicate is through the “chat” feature of the D2L program. You will need speakers to hear the webinar. Most computers have these internally in the computer. You do not need a camera or microphone for the actual webinar but you will need them to take the final exam for the course.  You will be able to see the instructor but he/she will not be able to see you. Notebooks, iPads and smart phones CANNOT be used for this webinar.
