Easy Author is a powerful and easy to use plugin that lets you acknowledge guest blogger and authors as a whole. Basically all you have to do is fill out a form in the wordpress visual editor, add author information in the required fields and your done. It has php and shortcode support so you can add author meta and data anytime and anyware.
The plugin comes with a styled box that is editable and customisable or can be disabled on the Easy Author settings page but probably the greatest feature is that you can grab individual author meta and data for example if you wanted the authors name you could simply add this PHP <?php echo easy_author(name, $post_id); ?> or this wordpress shortcode [ea value=”name”] and its not only just the name value you can grab, it can also be the authors email, bio, facebook URL , Twitter URL , LinkedIn URL , Google+ URL or their websites URL .
