Display feed for category in page, use simplepie and import feed 
from external site and display it in category page.
This add new fields to category: the url of feed and the title

<h3>Upgrade</h3>
I am experiencing some problem, deactivate and reactivate the module 
should fix those. Be carefull, just make a backup of table data 
(prefix_category_ext_feed), deactivate plugin, then reactivate. 
Thus if data about feed is not available anymore, just replace 
the table.

Just like the normal WordPress site feed, wordpress categories and tags also has feeds. The category feed is located at <code>site.url/category/categoryname/feed</code>. This plugin automatically adds the RSS feed link to the current post categories after the post content. By default the plugin shows category feed link on single posts. You can change it’s settings to show it on other pages, such as archives as well. You can change it’s title in WP-Admin –> Settings –> Follow Category Feeds.
