Unilica is a free course networking site for educators and students!
. . .
Unilica provides an unique environment for educators and students in which users can interact academically. This interaction
lowers the barrier between students and educators.
I have used Unilica for 2 semesters now, and am very pleased with its features and its usefulness as a course management system. Students love it, and I do too. I'm happy to recommend it to instructors wanting a better on-line course management experience.
