I somewhat suck with admin stuff so test this carefully. I had some issues with userst coming up in dropdown, but it fails with default meta box as well - probably because of my messed up test stack.



add_action( 'admin_menu', 'remove_author_box' );
add_action( 'post_submitbox_misc_actions', 'author_in_publish' );
function remove_author_box() { remove_meta_box( 'authorp', 'post', 'normal' );
}
function author_in_publish() { global $post_ID; $post = get_post( $post_ID ); echo '<p class="misc-pub-section">
Author: '; post_author_meta_box( $post ); echo '</p>
';
}
