First, copy (CTRL/C) the URL (web address from address bar of your browser) for your non-FASO blog. It will look something like this:

• under Navigation Label, replace the word Link with your desired name on your site (such as Blog, Blogspot etc) 
• under URL, replace the URL there by pasting (CTRL/V) your blog URL
