danielmain on "Function to add user to post as author once registered"

Hello,

I am trying to find a function that I can add to my functions.php file to add a user to a post as an author once that user registers on my site. The only solution that I have found to this was to install a plugin such as Co-Authors Plus and then manually assign the user to the post as an author. I would do this, but the admin user will not be able to add the new user to the post at all times, and I cannot give the new user a level of permission to view any other posts. Thanks for any help!
