In order for another website to display your RSS feed, the other website will have to get their web developer to create some code to read (parse) the feed from your website and display it.

What you will need to do, is send them the link to the feed. This link can be located by clicking on the icon located in the footer of your website, or you can just tell them the feed's URL is:

www.yourdomain.com/rss.xml for your articles, and
www.yourdomain.com/blog/rss.xml for your Blogs

where "yourdomain.com" is the domain name you use for your website.
