The Cool Author Box plugin adds information about the author to the bottom of the content of posts and/or pages. The information is gathered from the profile info set inside WordPress.
Items displayed are:
<ul>
<li>Display name of the author of the post or page</li>
<li>Gravatar of the author (set at www.gravatar.com)</li>
<li>Link to other posts by the same author</li>
<li>Link to author’s website</li>
</ul>
To make the author box appear you need to activa the plugin and go to the Cool Author Box settings under Settings and select if the box should appear under posts, pages or both.
