By default, WordPress requires users to confirm their new email address by clicking a link sent to the new email when changing it from the dashboard. 
This plugin disables this confirmation process and instantly applies the new email address.
It also disables the “email changed” notification email that is sent to the user after the change.
<h3>Features</h3>
<ul>
<li>Bypasses the email confirmation process in the user profile page.</li>
<li>Disables the post-update notification email sent by WordPress core.</li>
<li>No configuration needed. Just activate it and it works.</li>
</ul>

Relative URL applies the <code>wp_make_link_relative</code> function to links (posts, categories, pages, etc.) to convert them to relative URLs. Useful for developers when debugging local WordPress instance on a mobile device (iPad, iPhone, etc.).
Notice: This plugin SHOULD be used for local development only. I haven’t tested on a production environment; it may work with some issues, like unwanted URLs in RSS feed or sharing URLs are replaced with relative URLs, etc.
More information please visit my <a href="https://sparanoid.com/work/relative-url/" rel="nofollow ugc">site</a>.
For example:
<pre><code>http://localhost:8080/wp/
</code></pre>
Will be converted to:
<pre><code>/wp/
</code></pre>
And..
<pre><code>http://localhost:8080/wp/2012/09/01/hello-world/
</code></pre>
Will be converted to:
<pre><code>/wp/2012/09/01/hello-world/
</code></pre>
And..
<pre><code>http://localhost:8080/wp/wp-content/themes/twentyeleven/style.css
</code></pre>
Will be converted to:
<pre><code>/wp/wp-content/themes/twentyeleven/style.css
</code></pre>
Then after activating this plugin, you can simply access your local instance using <code>http://10.0.1.5:8888/wp/</code> on your iPad or other mobile devices without having styles and navigation issue.
