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.
