<p>With this plugin, administrators can change the default author base in the registered users profile url, and the author slug of each user.<br />
Changing an author slug is a good thing for security (if your login is “This Is Me”, your slug will be “this-is-me”, a bit easy to guess).<br />
The plugin adds 2 fields for this purpose, one in permalinks settings, the other in a user profile.</p>
<ul>
<li>Default: <em>example.com/author_base/author_nicename/</em></li>
<li>Customized: <em>example.com/jedi/obiwan/</em></li>
</ul>
<h4>How to edit the slugs</h4>
<ul>
<li>Go to <em>Settings</em> > <em>Permalinks</em> to edit the author base: “author” => “jedi”</li>
<li>Go to <em>Users</em> > <em>“Any user profile”</em> to edit the user slug: “agent-smith” => “obiwan”</li>
</ul>

<p>This plugin removes the ‘/blog’ slug from the main site permalinks of a sub-folder multisite install. The intended purpose for this plugin<br />
is for multilingual installations where the main site is the default language (although I’m sure there are other applications).  These sites<br />
are of often for businesses where having the ‘/blog’ in the permalink (URL) does not make sense.</p>
<p>‘/blog’ is automatically removed from the main site permalinks upon plugin activation.</p>
<p>‘/blog’ is automatically restored in permalinks upon plugin deactivation.</p>
