DigiCampus is a Moodle-based LMS used mostly by the universities that are members of the DigiCampus consortium in Finland. DigiCampus is mostly used for open and cross-institutional studies. Anyone can independently create a user account for themselves on DigiCampus platform, but access to the courses varies.
I find DigiCampus very useful when I am teaching MOOCs or open online courses. The LMS in my own university is very closed, and practically restricted to the staff and students of our own university only, so Digicampus serves as an open alternative for me and my students.
