RSS Submit is a Windows tool that posts your RSS automatically in the main RSS search engines.
You'll be able to type in several feeds at the same time, and you'll only have to do this once. Also, it can be easily integrated with Technorati and Feedburner so that you can follow your feed's statistics.
Once you've added all your feeds to the list, they'll automatically be added to more than 100 RSS search engines that are compatible with the app. RSS Submit is a great application for anyone who wants to boost their website's popularity in this new web 2.0 era.
