Summary

The Co-Authors plugin allows multiple authors to be attributed to a single article. Once attributed, they are listed in the article footer and the article shows up on each individual's author page and in their RSS  feed.

Use

Using Co-Authors happens all within the individual post editor. One of the additional widget boxes below the main editing area is entitled "Post Author(s)". In that box there is a dropdown where the individual author can be changed. Directly below, there is a button which when selected adds another dropdown in which another author can be selected for the article.

Bugs

There is a small problem that occurs when an author with a role status above that of "Contributor", so "Editor" and "Admin", try to co-write an article with an author with the role status of "Contributor. When an"Admin" or "Editor" adds a "Contributor" as an author of a shared article, the "Contributor" will be able to access the article and view it, but when s/he goes to save any changes s/he will be taken to an error page saying s/he doesn't have permission to edit the article. Somehow the article role permission is set to the first person listed in the multi-author list. If the authors are reversed, so that the "Contributor" is listed as the first author and the "Admin" or "Editor" as second author, the "Contributor" will be able to edit and save changes normally. It should be noted that this does not mean the authors have to be published in this order. Once the "Contributor" is done making changes to the article, the author order can be altered before publishing.

Update

There are no modifications to this plugin, so upgrading it is as simple as deactivating, replacing the files with the upgrade, and reactivating.
