Hi,
I have made some changes to extend the authorRequirements plugin. This plugin now allows certain author fields to be optional, such as the author email and family_name (last name). It also uses the context’s default country for new authors. Additionally, the following fields have been modified: the contributor role selection is hidden (auto-selecting the Author group), the biography field is hidden (converted to a hidden input), the URL field is hidden (converted to a hidden input), and the preferred public name field is hidden (converted to a hidden input).
