Being the mildly technically, slightly geeky type, I was ashamed that I didn't really understand what RSS was. I was pretty sure I knew what it did, turns out I was right :), but I didn't know how to really access them once they were "feeding" to you. So after a quick Google search I am now fully informed and thought I would shorten the process for the other three people that read the blog!

Hope you enjoy and add me to your new RSS reader soon!
