We use Learning Cloud for our virtual classrooms each semester, it is so easy to set up lessons/lectures in minutes instead of hours or days.
It's seamless integration with Moodle has also been great! It would be very helpful if there were less limitations (eg I can't assign quizzes to my class). Our student population is diverse and as such we have many international students who may not understand English well. The fact that you are able to create your own language packs means this isn't an issue anymore.
