Updated plugins
Achievements for WordPress gamifies your WordPress site with challenges, badges, and points.
Co-Authors Plus allows you to assign multiple bylines to posts, pages, and custom post types via a search-as-you-type input box.
Document Feedback allows you to get feedback from readers on the documentation you write.
Not sure what the point is of the first one… the featured image is automatically included in the RSS feed for the post – at least it seems to be doing on our site. Does the featured image not form part of the post itself? If so it would always be included in the RSS without the need for a plugin.
Actually, quite a few themes don’t display featured images within the post. For example, Twenty Eleven displays the featured image instead of the header image on the post page.
I will definitely be checking out that Co-authors plugin. Keep up the good work.
