A new feature has been introduced whereby you can have a feed from a different domain than that of your website. For example, you can have your site listed as www.example.org, and your feed coming from a service such as Feedburner. (This was technically possible before with feed redirection enabled on your site, but practically speaking was problematic).
The updated feed settings page now allows you to specify these URLs separately.
This also means links to your site from inConversation can point directly to your blog when your blog is in a sub-directory of your site, for example, www.inconversation.org/blog/ – as opposed to www.inconversation.org/.
