Adds copyright notice at end of articles in full text RSS feeds, with back links to the blog and original article.
A notice gets attached at the bottom of feed articles like this 
Original Article: Title of Article (linked to permalink) 
Copyright Year. Blog Title (linked). All Rights Reserved
Your Blog title is linked to your blog Url. Your article title is linked to the article permalink.
Blog copyright notices are important as your feed gets freely distributed across the web and is republished without permission by RSS scrappers and autoblogs. After using this plugin, now RSS scrappers will link back to your site, which will suggest to search engines that your blog and article was the original source.

Disable Feeds WP is a WordPress plugin to disable all RSS/Atom/RDF WordPress feeds on your website/blog. It is very useful if you use WordPress purely as a content management system (and not for blogging). All requests for feeds will be redirected to the corresponding HTML content.
There are a couple of options to tweak the plugin’s behavior – go to <code>Settings -> Reading</code> to see them.
Here’s a link to the documentation for the plugin. This will help you learn more about its features and how to use it.
