An award-winning LMS (Learning Management System) for teachers and school administrators.

While I am new to Schoology, I have heard that it is taking the educational world by storm as it seamlessly
integrates with third-party software such as Moodle, GoogleApps, TurnItIn, BlackBoard Collaborate and PowerSchool.

It looks and feels like Edmodo but allows custom branding and domains. Obviously, it comes at a price.

Feel free to have a look at it here
