Please help by contributing to the GitHub repository Edit Usernames on GitHub
The Edit Usernames plugin allows WordPress admins and WooCommerce managers to edit the users’ usernames through the admin dashboard. All references to previous username are changed after editing, including comment author.
Note: Editing of your own username and those of Super Admins are currently disallowed.
