This plug-in redirects requests to the main or comment feeds, and only theses two, to Feedburner or a similar service. In comparision to the original Feedsmith-plug-in is has three advantages:
<ol>
<li>
It redirects only the two main feeds of the blog and not all. The category, tag and author feeds are still accessible
</li>
<li>
If you need access to the original blog feed you can add the URL parameter “noredirect” (i.e. /feed/?noredirect) to your feed address and it will not forward your request.
</li>
<li>
The Plugin is more integrated into the administration interface. It adds its settings to the default “reading” settings pages and do not create an own page.
</li>
</ol>
