Create RSS feeds even with enclosures and publish them, using RSS Builder
If your web site is not driven by a database or for any reason you can not have an automatically created RSS Feed, you can try RSS Builder.
This will allow you to create manually RSS news feeds and podcasts.
It provides a simple enough interface that lets you add topics, links, content, and enclosures.
You can publish the RSS feed to your web server even using a built-in FTP client.
