Hello to all, this is my first message here. I finished reading the book a few days ago, and I must to say that is very helpful to newbies. I had a lack of knowledge about this business that the book has covered.

I think that the point is not if you like more or less the job of Alex but If he has a good knowledge of this world and he know how to transmit it to others. And he has made a great job with this book.

Regards and sorry for my english.
