Hi,
first of all, excuse me to write to your mailing list in English, but I can not speak Portuguese and in my opinion the following information could be interesting for you.
We have released today, a new version of the offline version of the Wikipedia in Portuguese. This includes all encyclopaedic articles, all categories and pictures (thumbnails).
This allows everyone with a PC (Windows, OSX, Linux) to enjoy Wikipedia articles without Internet; like for example in the middle of the desert, during a flight, on the seas... or in jail.
You can download the Wikipedia offline in Portuguese (8.1GB) here: * http://download.kiwix.org/portable/wikipedia_pt_all.zip * http://download.kiwix.org/portable/wikipedia_pt_all.zip.torrent
Here is a demonstration how the content looks like: http://library.kiwix.org/wikipedia_pt_all/

Kind regards Emmanuel
