An awesome post, I just passed this onto a university student who was doing a little research on that. And he in fact bought me lunch because I discovered it for him.... smile. So let me reword that: Thanks for the treat! But yeah Thanks for spending the time to discuss this, I feel strongly about it and enjoy learning more on this topic. If possible, as you become expertise, would you mind updating your blog with more information? It is highly helpful for me. Big thumb up for this share!
