If it were possible, I would recommend you to a top spot in both the teaching software and general software halls of fame. You gals and guys are the very best the world has to offer! I am hopelessly addicted and probably moving too fast. I just love watching my percentages rise and can't get enough of it. I am interested in the learning process from a neuroscientific point of view and I am witnessing numerous additions to my long-term memory. As a young child would, by immersion in the Spanish language, I am also adding new listening and speaking abilities every day to Broca's and Wernicke's areas in my most important asset, my brain. What I have learned is that the most important thing in life is to continue learning. ¡Saludos y congratulaciones a todos!
