I am looking for a way to allow certain users to assign themselves a custom role I've created in the system wide context.
For example, some content management systems allow for entry of an "RSVP code" or similar for users to add a role to their own account.
Is something similar available in Moodle, or is there another recommended way to achieve this? I know you can self-enrol in a course, but I'm not sure about adding a role system-wide.
We are using Moodle 2.6.2. Thanks in advance!
