What if there are no teachers or students on-line?
Stay on i2istudy and learn foreign languages with the i2i-robot.
Write a message to the person you want to study with, in your letter specify the time which is most suitable for your lesson.
Invite a friend. If your friend lives in another country, maybe he or she would be interested in studying your native language, and you can study their native language. You can pair off as a Teacher and a Student and no longer worry about finding a friend for conversations!
