<p>The external links plugin for WordPress lets you process outgoing links differently from internal links.</p>
<h4>Usage</h4>
<p>Under Settings / External Links, you can configure the plugin to:</p>
<ul>
<li>Process all outgoing links, rather than only those within your entries’ content and text widgets.</li>
<li>Add an external link icon to outgoing links. You can use a class=”no_icon” attribute on links to override this.</li>
<li>Add rel=nofollow to the links. (Note: You can use a rel=”follow” attribute on links to override this.)</li>
<li>Open outgoing links in new windows. Note that this can damage your visitor’s trust towards your site in that they can think your site used a pop-under.</li>
<li>Turn on “autolinks” functionality.</li>
<li>Domains/subdomains you wish to Exclude from processing.</li>
</ul>
<h4>Auto Links</h4>
<p>The Autolink functionality automatically converts urls to hyperlinked urls in post/page content, excerpts and text widgets.</p>
<p>Before:</p>

<p>After:</p>
<blockquote>
