I use moodle version 3.10.1.
Actually, my needs are not very demanding. I want that everyone can give a feedback without enrolement or without a specific moodle login. And this feedback can not be on the frontpage, it must be in a courseroom.
Therfore I tried to do that with the guest role. In addition, I gave this role the following right:
When I change my own role (admin) to Guest, then I can see the link to answer the questions. If I log out and then login as a real "guest" again and visit the same course page with the feedback activity, the link to answer the questions is NOT visible.
I really tried to solve it, but I stuck with this problem.
Thank you very much for your help.
