How do I change the RSS feed for my Largo site?
In Appearance > Theme Options > Basic Settings you can change the feed URL.
Look for the Feed URL field on the first page of theme options. This is a link to the main RSS feed for your site. By default, this will be http://yoursite.com/feed but if you use a feed management and/or analytics tool (such as Feedburner), you can replace the default link here and it will be used in all relevant places on your Largo site.
TIP: If you use MailChimp for your email newsletter, Largo also adds a custom RSS feed that includes thumbnail images in a format that MailChimp will understand. You can find that at http://yoursite.com/?feed=mailchimp.
