RSS URL
In the RSS URL box you can put any feed URL (probably a Feedburner URL). For example http://feeds2.feedburner.com/mysite.
Developer
To use the RSS URL you need to put the following code where you would normally put your RSS URL code.
<?php if(function_exists('wtf_rss_url')) wtf_rss_url(); ?>
This will echo the RSS URL.
