Whenever you use Collaboration to share your book with another Atticus user, you give that person permission to “access” your book in one of three roles: Editor, Co-Writer and Beta-Reader.
If you no longer want to share your work, or want to remove yourself from someone else’s book, “remove access” allows you to do that.
How to remove yourself (or someone else) from a shared book:
In the Collaboration Tab, locate the book you want to “remove access” from.
Click the three dots in the lower-right corner of the book’s info card.
Select Remove Access to remove yourself/someone from the project.
This will immediately end access to the book.
