Adds a shortcode, series-tag, that you can use to create a list of all posts 
that are tagged with whatever tag you pass in.
Series Tag was written to allow you to tag a series of posts with the same tag, 
and then easily link between them without having to manually create links at the 
bottom of each post.
Links are created in date published order starting at the earliest date. All post 
titles are links to the permalink of the post except for the current post which just has its title displayed.

Series Tag

Simple Course Creator lets you group WordPress posts into courses using a custom taxonomy, then automatically displays a linked list of all posts in the same course within each post’s content.
Features
<ul>
<li>Create unlimited courses from the Posts menu — just like categories and tags</li>
<li>Assign posts to a course from the edit post screen or the manage posts screen</li>
<li>Display the course listing above content, below, or both</li>
<li>Choose between numbered list, bullet list, or no list indicator</li>
<li>Sort the listing by date, title, author, last modified, comment count, or random</li>
<li>Style the current post in the listing as bold, italic, or strikethrough</li>
<li>Optionally collapse the listing behind a toggle link (JavaScript)</li>
</ul>
Post Meta
Show author and publish date beneath each item in the course listing. Both are enabled by default and can be toggled from the settings page.
Front Display
On the blog home, archive pages, and search results, indicate that a post belongs to a course. Enabled by default and can be toggled from the settings page.
Customization
Style the course box, post meta output, and front display indicator directly from the WordPress Customizer — no custom CSS required. For deeper customization, override the plugin’s template files in your active theme.
Create a directory called <code>scc_templates</code> in the root of your active theme and copy any files from the plugin’s <code>includes/scc_templates/</code> directory into it. Theme files take priority over plugin files.

Simple Course Creator

Organize WordPress posts into courses and display a course listing within each post.
