The Aggregator Module is included as part of your YaleSite and Drupal Core. This module pulls news, text, videos, etc. from the RSS feeds of other web sites so it can be displayed as part of your site. All you need is a fully-qualified URL of the RSS feed you want to pull into your site with the proper filename extensions e.g. .rss, .xml and .rdf. The feed can be displayed using the Module Block that is generated for every feed you have subscribed to (disabled by default). You can also create categories for your feeds.
Please see the Step-by-Step instructions from OSTraining (left sidebar ->) to learn how to use the Aggregator Module.
