Amadeu!
I've just come into contact with your wonderful site, and am absorbed by it! It's so rich! But I still haven't seen two parts that will take more of my time: the podcasts and your articles and essays. I'll certainly write again here to tell you what I think of them, okay?
As I was looking at the book covers, I remembered the good old times when I started studying English on my own. I bought one of the series -- Time for English, student's version -- and filled it in from cover to cover. That was great learning, which I'll never forget!
Thanks for presenting us with such a nice site!
All the very best to you.
And I wish you a WONDERFUL 2011!
