Copy the following snippet and edit the message on line 5. Once done, paste it on your functions.php file and save.
function wptutsplus_text_after_title( $post_type ) { ?> <div class="after-title-help postbox"> <h3>Using this screen</h3> <div class="inside"> <p>Use this screen to add new articles or edit existing ones. Make sure you click 'Publish' to publish a new article once you've added it, or 'Update' to save any changes.</p> </div><!-- .inside --> </div><!-- .postbox --> <?php } add_action( 'edit_form_after_title', 'wptutsplus_text_after_title' );
