A basic default category plugin. 
The main purpose of this plugin is to provide different default categories on a per user basis.
I was looking for a plugin to set a different default category for my flickr posts (through XMLRPC API). 
And there was no built-in function to set a default category to a particular user.
This plugin is very simple :
<ul>
<li>any author can set it’s own default category (user can <code>edit_posts</code>)</li>
<li>any admin can modify an author default category (user can <code>edit_user</code>)</li>
<li>anywhere in WordPress a user get it’s default category where applicable : posts, API posts, … except in the writing settings page</li>
</ul>

Author Default Category

Any author (user can edit posts) can set its own default category on his profil page.

This plugin does more than just using the <code>xmlrpc_enabled</code> hook, because that is only used “To disable XML-RPC methods that require authentication”.
Activating this plugin will also disable pingbacks, trackbacks, and Really Simple Discovery (RSD), because these rely on XML-RPC.
It works with any webserver, because it does not use the .htaccess file.
<h4>Testing the plugin</h4>
From the command line you can test if the plugin is working correctly using <a href="https://curl.haxx.se/" rel="nofollow ugc">cURL</a>. Replace the <code>example.com</code> link to match your website:
<pre><code>curl -d '<?xml version="1.0"?><methodCall><methodName>system.listMethods</methodName><params><param><value><string/></value></param></params></methodCall>' https://example.com/xmlrpc.php
</code></pre>
This should only return the following methods: 
– <code>system.multicall</code> 
– <code>system.listMethods</code> 
– <code>system.getCapabilities</code>

Remove XML-RPC Methods

Remove all WordPress methods from the XML-RPC API to increase security.
