Web developer Pete Freitag has written up a very easy to follow tutorial that will show you how to roll your own RSS feed.
If you can learn HTML, you can easily learn how to build your own RSS 2.0 feeds. I'll take you through the steps to creating an RSS feed from scratch.
Most blogging and publishing services will provide templates that will do this for you. However, if you've ever tried to edit those templates without knowing what everything does, you'll know that you can quickly get into trouble. This tutorial is very easy to follow, provided you know a bit of HTML and how markup works. Even if you don't actually use it, learning about how RSS works could really help if you ever need to do something custom with your feeds.
