languages in belgium
The country is basically divided in three different languages (Dutch in the North part, French in the South part and German in a little part (5% of the territory) ), why make things simple when they can be complicated ;-),but most people have an acceptable level in English as well...
I personnaly could buy your books in english on amazon.fr.
PS : Thanks for TI ;-)
