A snippet of code packed in a plugin to render the WordPress RSS widget as a shortcode.
This allows you to display external or related content on its own page.
In combination with Yahoo! Pipes, or another RSS magic service, you can create nice collections of articles for your readers on a separate page.
This plugin does not create WordPress posts from feed items.

WordPress RSS Shortcode

A shortcode to render an RSS feed in a post/page

Feed(Aggre)gator takes a list of RSS feeds and creates a single list of RSS items from those feeds to be displayed as a widget. You can select how many items you want to display and whether you want to show the entries chronologically or you want to show the latest entries from each feed listed.
You can also opt to display the date associated with the RSS item as well as the author of the item.
