# The author and the referee profile

In Nestor, all users are considered potential authors or referees. Consequently, author and referee profiles are unique. For a given journal:

- when submitting a paper, all users will share the configuration of the author profile
- when reviewing a paper, all users will share the configuration of the referee profile

The main focus of those pages is the visibility regarding peer review. Those configurations can be found here:
