This plugin was developed because I have one blog with multiple authors who have 
their own categories. The users’ category access is administered by the Authors2Categories 
in Tools panel of the admin.
Select the user. Click on Edit User (Tools>Authors2Categories) and select the categories he/she 
are allowed to post to. Click on Save when you are done.

This plugin allows you to display an unordered list of post (or custom post type) links (with title, featured image and exceprt) to a specific author (or multiple authors), category (or multiple categories) and tag (or multiple tags). It can be called either with a shortcode or from within a theme file.
To call it with a shortcode, use <code>[latest]</code> below are the attributes you can use with this shortcode: 
* Authors: 
 [latest author=”username or multiple usernames separated by comma”] 
* Category: 
 [latest category=”category name or names separated by comma”] 
* Tag: 
 [latest tag=”tag name or names separated by comma”] 
* Post Type: 
 [latest post_type=”post type name”] 
* Show Posts: 
 [latest show=”number of posts to show”] 
* Show Excerpt: 
 [latest excerpt=”true (default is false)”] 
* Show Thumbnail: 
 [latest thumbnail=”true (default is false)”]
To call it from within a theme template, you have to wrap it in this PHP function: <code><?php echo do_shortcode('your shortcode goes here'); ?></code>
