Problemas com a administração do Moodle

Tim,
Great resource! I have been looking for something like that for a long time. Documentation could be improved. I could't find the forum in the AutoView site.
I have a doubt: how can I change the language of the presentation (to Brazilian Portuguese - pt_br)? I found the newlang.html and genertated the text file, but I don't know where to put it. Could you help me?
Thanks for the good work,
Paulo Penteado, Brazil
