I am using a feedback to create a "contact us" form that is anonymous and open to guest users.
I (obviously) added a captcha question, I have set the private/public key in the server settings but:
1) The captcha shown is very simple (just 3-4 numbers);
2) It always ends up true, whatever the answer.
Did I miss something or it's a bug ? I have tried captcha for self-registration and although it remains pretty weak (only 3-4 digits) it works.
Thanks, Antonello (Moodle 2.7)
