This is a plugin originally authored by
Steve Smith. It detects all ways to access your original WordPress feeds and redirects them to your FeedBurner feed. I enhanced it base on the FeedBurner FeedSmith and now it can redirects feeds for category and tag also.
1.Download the plugin and expand it to the plugin folder(wp-content/plugins/).
2.Login into the WordPress administration area and go to the plugin page.
3.Click the activate link of the 'Feedburner feedsmith extend' plugin.
4.You can then go to Settings -> FeedBurner FeedSmith Extend to configure all your FeedBurner feeds.
