Assign multiple signatures to posts, pages and custom fields via the input window. This kind of labels appear in the records, on the archive pages of authors and their news feeds. Co-authors extension allows you to edit posts and to interact with authors, co-authors who can be members, as well as edit the record, even if they themselves are not published.
Add authors as a signature without creating WordPress user accounts. Just create a guest access and profile for him as a writer and confirm the signature in the standard way.
In the frontend, use tags, and their templates of the plugin Co-Authors Plus using of lists anywhere.
This solution is a completely redesigned plugin originally developed at Shepherd Interactive (2007).
