Skype has a "Chat" area that our enrolled students can use in "asynchronous" mode, which means they don't need to be online at the same time to type their answers to the discussion questions and reply to other students. Skype also provides "synchronous" group video calls, meaning all of our enrolled students should agree on a set time to be online together. By default, our students use Skype's web version, but if their internet connection is slow, we recommend installing Skype on PCs & Macs and on Android smartphones & iPhones. Skype also allows users to share their screen, which is useful for sharing these lessons and other materials.
