Hi, I am Guy Léger from Cameroon... I am sorry to be late to introduce myself because I am an active member since several months. But the real cause is that I have never took the time to explore the forum website in deep. I have a teacher's diploma for technical education, a master degree in quality management and an mba in human resources. I have 8 years of experience in teaching, 3 years in qa/qc and 2 years as a web designer and a blogger. I am very happy to join this helpfull forum.
