Studeous is a new service that teachers can use to create online discussion forums for their courses. In your Studeous account you can create a discussion forum for each of the courses that you teach. In addition to using Studeous as a discussion forum you can create an announcements page. If you upgrade to a paid account you can post files and images too (the free version limits you to two files). Students can join your forum by entering the access code for your course or you can send them invitations via email.
Applications for Education
Studeous is not as robust as some similar services like Edmodo. That said, if you're looking for a quick and easy way to create a discussion forum for your courses Studeous might be for you.
