creating messages that appear after content is created
This could be done with some code in a custom module:

hook_node_insert($node) {
    if($node-&gt;type=='my_content_type') {
        drupal_set_message(t('New content created: :link', array(':link' =&gt; l($node-&gt;title, 'node/'.$node-&gt;nid))));
    }
}
