As this is about translations, moving it here.
Thank you for showing an interest in helping to improve Linux Mint for Portuguese users! The translations for programs developed by Linux Mint are done on Launchpad, see here: https://translations.launchpad.net/linu ... a/+lang/pt
. If you create a Launchpad account, you can request to join the team of translators on the linked Portuguese translation team for Linux Mint page.
Most applications are translated upstream, by the Ubuntu translation teams. With a Launchpad account you can also join there to help translate. The homepage for that team is here: https://launchpad.net/~ubuntu-l10n-pt
If instead of Portuguese, you meant Brazilian Portuguese, the links instead are:https://translations.launchpad.net/linu ... lang/pt_BRhttps://launchpad.net/~ubuntu-l10n-pt-br
For some more background on how translations are done and managed, see viewtopic.php?f=43&t=102330#p580665
. Just ignore the bits specific to Khmer or that for Khmer there is no translation team (as for Portuguese there is a translation team).
