I set up an assignment of the type Online-text in a course that allows guest access without an enrolment key. I found that when someone entered the course using guest access, he or she could click on the "Edit my submission" button on that assignment page to type in any text in the HTML Editor.
Is the Assignment module supposed to work like that (i.e. allowing online text submission by guest users)? Or is it only an error on my part? I think it must be a program bug - unregistered/unenrolled users should be prevented from making online text submission in the Assignment Activity. What do other users think?
