Front page
From MoodleDocs
The front page is the initial page seen by someone reaching a Moodle site.
The site settings determine which user roles can reach it. For example, the demo.moodle.org allows visitors (guests) to see it's front page and asks them to log in. A user clicking on the course is taken to the "Returning to this website" Moodle login in screen. Other sites may require a login before showing the front page.
Many functions of a front page are similar to those found in a course.
