I thought I used to be able to audit a course, free of putting in financial (credit card) information. It was easy to use. Now, I am required to do a "free trial" and would require to cancel after 7 days... or else pay for the course. Question - do you still offer free auditing of courses, or not? Perhaps my recollection of how coursea works is not correct, or possible I was always using edx courses for free auditing of courses. Please explain the policy of coursea - do you offer free auditing of courses for any time limit, or are members required to pay for courses after 7 days ??
