Dear Marcos,
Please allow me to introduce my self: my name is Andre Krepsky, I am a brazilian citizen who openly advocates about open souce paradigm and, additionaly, lived in New Zealand for three years.
I have recently realized PgAdmin does not have a working translation to Brazilian Portuguese, which would be absolutely great for my students at the Database Fundamentals course, currently lectured at Estacio University.
Willing to contribute to this fantastic project, I would like to humbly help finishing the pgadmin3.po file.
Please let me now whether I could help you up.
I am looking forward to hearing from you.
Best regards
