What WP More Feeds does?
WP More Feeds just simply generate more feed links for category page and tag page, you can call it Category Feed and Tag Feed. That will give the readers more choices.
How to find the feeds?
WordPress supports RSS feed, if you have a look at the source page of this page , you may find some code like this in the head:
<pre><code><link rel="alternate" type="application/rss+xml" title="MashGet RSS Feed" href="http://feeds.feedburner.com/mashget/" />
</code></pre>
That’s it, the RSS Feed, which is for the whole site. If you install WP More Feeds, you can get another feed on category or tag pages.
Actually, most browers will find this feed for you today, for Firefox, you’ll find a RSS icon on the right side of the address bar. See the <a href="https://wordpress.org/extend/plugins/wp-more-feeds/screenshots/" rel="ugc">ScreenShots</a>
