I changed the default author of a node to blank (' ') for the needs of my project. So, currently when I create a node, "Authored by" field is empty. Then, I could assign author and this works fine - the assigned author is displayed within the Authoring information.
But when I edit the article, the 'Authored by' field is again blank, so if I just want to change something in the body, I would need to assign author again.
Any suggestions how to make the field to remember its value?
