I live in Hanoi, Vietnam, and am doing a masters in GIS at Belfast Uni (distance learning of course) . But I can't download the book because vietnam is not in the list of countries you will accept payment from.

Hope you can rectify this.

Just realised that the countries missing from the list are probably the ones there are no book distribution deals with. However, Option 1 is soft copy only.

Anyway, I used a UK account number to sort it out, but I will say that the appeal of this book is especially strong developing nations where free software is perhaps taken more seriously than back in the West.

1st edition was super by the way.
