Every student needs an e-mail account.
You will not be able to use accounts belonging to other students because of the confusion this causes. You must have an E-mail address prior to starting the class as a number of issues need to be communicated directly to you. Check with your ISP if you do not know what your E-mail address is. If you already have an E-mail account, you may use this address for this online course. These free sites post ads on their services as a way of supporting the services they provide.
