Quote This is yet another quote plugin. It has been a script I’ve used on my personal blog for a few years that I figured I’d share with the rest of the WordPress community.
Basically, it lets you show quotations on your blog in one of three ways:
<ul>
<li><code>quote_this()</code> template tag for your theme template files.</li>
<li><code>[quote-this]</code> shortcode for adding it to your posts and pages.</li>
<li>Quote This widget for use in widget areas.</li>
</ul>

Quote This

Allows the user to call random quotes with the quote_this() function, [quote-this] shortcode, or Quote This widget.

When you add this plugin, a metabox is added to the edit post/page screens that allows you to disable ShortCodes in that one particular post/page. Admittedly, this plugin may not be widely needed by the general public. However if you are a plugin developer or documenter, you might find it very useful.
If you want to show examples of how to use a ShortCode and not have that ShortCode activate upon display of the post, this plugin will come to your rescue. The SCuD will disable all ShortCode processing for any post.
SCuD is written to prevent any collateral damage. After the post content is displayed, it activates the all previously disabled ShortCodes again. This allows any ShortCodes that you may be using in sidebar widgets to process correctly.

SCuD – The ShortCode Disabler

Allows you to disable ShortCodes on a per post/page basis.
