Go to http://www.skype.com/en/ to establish a Skype account. You will be asked to provide a user name and an email address. Use your course alias for the user name (first part of your new gmail address) and your new course gmail account.
Once you have set up your Skype account, add ggatin as a contact. I will acknowledge the connection and add you to a class group discussion on Skype. We will use this as one available communication channel for the rest of the class.
