A Contributor is any user who has been granted access to another user's content, whether read-only or as a content contributor.
Contributor Only Access occurs when you have no current engagements with any organisations on Cloud Journals, meaning you can't create or modify your own content (i.e. journals, learning logs, etc.). However, you can still contribute to anyone who has invited you as a contributor to their content.
