I have looked around and have no clue of what an rss feed is. Is there a primer for what an rss feed is, how to get info from a site with one, and how to put one on my site? Do I just put any of the 5 url's in the link below in the widget? What happens after the rss feed is set up on my blog?
<?php bloginfo('rss2_url'); ?> http://codex.wordpress.org/WordPress_Feeds
The blog I need help with is nina80.wordpress.com.
