This plugin allows you to enter [author_bio] anywhere within the content of a post or page to display the biography of the author of that post or page. The output now contains HTML, which can be customised very easily with extra parameters – see Installation for a how-to – to sit around the bio, as defined in /wp-admin/profile.php. By default the shortcode produces the author of that post or page. However, extra parameters enable you to specify a different user whose bio you want to print out – see usage instructions. Feature requests welcomed with open arms!
