yonisink

yContributors creates a one-step author or contributors archive page that enables you to show any number of recent posts by each author, along with profile information pulled from each user’s wordpress user profile. This plugin shows all your members, either in table or descending form, with a jQuery searchable autocomplete-style (type and find) way to get to members. Options include excluding certain members, showing latest posts and author statistics. Also, works with User Photos Plugin (unrelated to this) to display profile photos.

Please note, as with every plugin or theme modification, you should do a backup of your files beforehand. Although we’ve tested this across many installs, we are not responsible for anything it does to your system and do not guarantee support.
