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.

Feed Excerpts For Divi is a simple plugin for the Divi Theme by Elegant Themes. This plugin provides excerpts for the Blog Post Feed when the Feed is set to show the Summary instead of Full Text.
WordPress filters out shortcodes when it is set to Summary, which leaves the feed content empty for posts using the Divi Builder. This plugin resolves that by generating an excerpt from the first Text Module on the post where the Divi Builder is enabled.
Sample RSS Feed: (http://feeds.feedburner.com/ferventsolutions/feed-excerpts-for-divi)

NOTE: This plugin is not necessary when using Full Text for the Feed
