With FeedForAll software, make your own RSS feeds, and upload them to your websites for people to subscribe to. FeedForAll does not submit RSS feeds. Download a free trial of FeedForAll software: http://www.feedforall.com/software.htm
To more directly address your questions, FFA doesn't auto-submit your published feed to RSS Aggregation sites but it does create the feed and allow you to upload it to your website. The process of then submitting it to aggregators is something that you would need to do separately.
