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>

This plugin adds an email subscription form anywhere on your WordPress website for your Feedburner RSS feed. Add it to the end of posts to increase your subscriber count. This plugin is an implementation of the FeedBurner Optin form found <a href="http://www.wpsquare.com/add-feedburner-optin-form-wordpress-blog/" rel="nofollow ugc">here</a>.
There are two different formats: a ‘main’ format for most applications, and a ‘sidebar’ format for putting the form into your sidebar or smaller areas.
