The FeedWordPress plugin lets you include external RSS feeds into your blog post stream.   This plugin is especially useful if you teaching a course, and want to aggregate content from individual student blogs into one central post stream, where class members can read and comment.

It also is a method to use if you want to post content once, and have it published on several (or many) other sites.

To use FeedWordPress, you will need to paste the URL for each feed you want to syndicate into the form seen below:

There are many configurations which you can set in the “Syndication” admin tab, including ways to handle categories and tags.  For example, if the external category does not exist locally, should the local site create this category, or put the post in another category.
