How do I change my site feed settings?

To enable or disable the site feed(s) for your blog, first go to the Settings | Site Feed tab.

Here, you'll have one simple option, where you can select how much of your content you want to syndicate. "Full" will put the entire content of each post in your site feed, while "Short" only includes an excerpt from the beginning of each post. The "None" option turns your site feed off entirely.

That one site feed may be enough for you, but if you want some more options, click on the "Advanced Mode" link.
