Extremely useful !

Hello, I picked up most of the podcasts through Itunes, and listen to them in my car. It's so interesting that I almost enjoy traffic !!!! I'm a Programme Manager, working in IT field in a US company. I'm living in Brazil, and from France in fact. I understand very well the effectiveness of yours explanations and tips. However I always try to adapt that to other cultural environment, and it's not that easy, in deed. Anyway, I learned a lot, and keep on listening to these podcasts regards
