<p>When a post is saved, the plugin adds the rel=”nofollow” attributes to post external links. The plugin also provides an apt checkbox to exclude a post from plugin’s action.</p>
<p>Links which already have a <em>rel</em> attribute are just ignored, so you can set some <em>dofollow</em>s are well.</p>
<p>By default, the plugin will only act on <em>posts</em>, no pages or other custom post types. To include (some of) them, use a code like the following, for ex. by putting it in your theme’s <em>functions.php</em>:</p>
<pre><code>add_filter( 'rnf_post_types', function( $post_types ) {
    return array( 'post', 'page' ); #specify all desired CPTs, comma-separated
});
</code></pre>
