Lesson 8 from this course refers to features which have significantly changed in Office 365. Specifically, Newsfeed, OneDrive, and Sites have moved to other location in Office 365. And to date, I cannot find Sites anywhere in Office 365. I emailed the author of the course in hopes of an answer. How can we study for the 77-419 test when the features have changed regarding community and Lesson 8? Perhaps someone reading this has an answer. Thanks.
