I've created a series of HotPot activities that I've put on our Moodle (v 2.1). I intended for them to be open to all, i.e. no need to have a username or password. They're not intended for assessment, just fun activities. Also a way of recruiting people to courses.
After setting them on the Moodle, however, I've discovered that, although access to the course is unrestricted, you need a password to access the individual exercises. How can I enable open access to the exercises?
