Let's see if I can explain this properly. * smile *
When your blog is open, go to "Design" at the right hand side at the top.
Click on it. You will see a page that says "My blogs, the name of your blog, and Overview".
Click on "B" in the upper left hand corner.
Scroll down to "Reading List' also on the left hand side, and click on this.
Click on the gear icon on the right hand side.
This will open a new page!
Choose "settings" for the blog you don't wish to follow anymore.
This will open a box which has "stop following this site".
I figured it out all by myself. I am a complete Genius!
