You can add an external (RSS) feed to your announcements for users to read. RSS, also known as Rich Site Summary or Really Simple Syndication, is a web feed format that publishes frequently updated information from external websites such as blogs, news headlines, audio, and video. RSS feeds benefit users who want to receive timely updates from favorite websites or to aggregate data from many sites.
Click the Announcements link.
In the sidebar, click the External Feed link to add a feed from another website or blog (via Tumblr, Blogger, and/or Wordpress) to the Announcement stream.
Paste the feed URL into the feed URL field. All new entries from that RSS feed will be added to Announcements.
Select what type of content you would like to post by selecting an option Full article.
You also have the option of choosing to add only posts with a specific phrase in the title by selecting the Only add posts with a specific phrase in the title checkbox [1]. Indicate which words or phrases you want posts from by typing in the text box below the checkbox . Click the Add Feed button [2].
Now that you have added the RSS feed, it will show up under the external feeds [1]. If you want to delete the external feed, click the X [2].
Note: You will have to wait until a new post is published on the external (RSS) feed before you can see it on the Announcement feed.
