This video shows a walkthrough of new functionality added to the Feeds node helper module. This effectively allows you to create feeds that have certain fields that act in the same way the prepopulate module does. You can craft certain URLs with properties defined by the site author in order to populate values that normally could not be imported via RSS and other feed types.

This video is shot in the context of ELMS and how this allows for creating an address for students to automatically import and associate these blog posts to their currently active exhibit.
