Simple aggregated RSS Feed with Pipes

Answering a question that was posed at work regarding RSS feeds and Yahoo Pipes.

Q: How can I make an aggregated RSS feed in Pipes?

A: If you have a set of RSS feeds you’d like to include in an aggregated feed, simply drag the fetch feed module into the workspace and click the addition (plus) button to add more source URLs for the module.  Then send the output to the pipe output. When you name and save the pipe, you’ll be able to get it as an RSS feed, or in a multitude of other formats.
