Well, as all of our packages are in Ubuntu's repos you can use the Ubuntu translation system (Rosetta) to help translate. I think a good place to get info is https://launchpad.net/~ubuntu-l10n-pt-br . One thing we definitely need is help is with helping other users on the forum and in general. Also, we currently don't have a Portuguese translation of the Bible that we can ship. It needs to be a freely distributable Sword module. If you want to get more info or contribute, the Ichthux mailing list is at http://www.crosswire.org/mailman/listinfo/ichthux-devel .
