Portuguese translations added:
http://forums.pligg.com/downloads.php?do=file&id=58 and post #2 updated to include it.
This was fun - I have no idea of what the Portuguese language would sound like - I used tips #1, #2 for majority of the translations and #3 for few words (sorry that I had to steal - as it was only few words)
If many start this like a game - Pligg admins will consider putting them into SVN too - making many people's life much easier - we can propose to have an admin option to just switch languages - think how good it would be to just change th whole language in a flash. It can happen only when many start contributing.
I also suggest people of that particular language to verify these files for any grammatic errors (Google translators are not always good!!!)
