Node Co-Authors
This module allows nodes to have multiple authors who share the same content editing and deletion rights as the original author. A co-author field is added to nodes, and users with appropriate permissions can assign or manage co-authors.
Allows for nodes to have additional co-authors that share the same rights over content as the author.
This module requires no configuration. A co_authors field is added to the node entity type. Just like the normal author field, only users with the administer nodes permission can edit it. Users with edit own <bundle> content or delete own <bundle> content permissions can also edit/delete nodes they are co-author of. The form & view display can be changed, but by default the field will be shown in the sidebar, after the author field.
