Just a quick question about the access code feature.
Is there a way to protect the sign up link form an unauthorized registration? We had to remove a few emails from the course because they were not on our list of registered students. However, we realized that these students can register again using different user names, as the sign up link is not password protected.
Do you have any plans in the near future to introduce the feature that requires an access code, as it used to be in the old version of the Coursesites ? And do you have any suggestions as far as how to deal with this problem now?
