There are some websites on the internet on which people provide or sell per-recorded language courses.
. t These are courses in a language that are based on a series of videos that provide teaching on various aspects of a language. But they don't give the buyer the ability to talk to the teacher, ask questions etc.. d Do any of you feel that this could be a useful aid to learning a language?

Would any italki users ever consider buying such a course? They usually do not cost very much money - perhaps £40 or so - and often involve 10 or so hours of video content for your money. If you would consider buying such a course, what sort of content would you most like to see covered?
