What is Opencampus?

Could you please elaborate on what Opencampus is? I've heard of it in the context of education and technology, but I'm not entirely sure what it entails. Is it a platform that connects students and educators globally? Does it offer virtual classrooms or online courses? I'm curious to know more about its features and how it's transforming the educational landscape. Could you provide some insights into how it works and what sets it apart from other similar platforms?
