I would like to display a blog-style page on my site as RSS format, so that people can subscribe to it in Feed Readers, etc. How would I go about doing that?
This is actually very easy. Simply add the following to the end of your page's URL, and it will display the pages output as an RSS feed:
?format=feed&type=rss
So if you for example have a blog at http://yoursite.org/blog then the RSS feed would be displayed at:
http://yoursite.org/blog?format=feed&type=rss
And that should do it!
