Non-member contributors to a project

Is it possilbe to generate a list of iNaturalist users who have contributed to a project but have not joined? The Australasian Fishes project contains observations from about 1600 people but only about 600 have joined, largely I suspect from me not personally inviting them in the early days of the project.

It’s a traditional project, right?

This list should show anyone who has an observation in the project:

Hi Charlie,

Thank you for your reply. I tried that, but the list gives 500 users only. The Australasian Fishes project has had contributions from more than 1600 people. I couldn’t see a “more” or “next page” button.
