Hi! I'm a member of the Portuguese Translation team and we would like to create a new translation variant (pt-ao90) but it does not have an ISO639 code. We're still writing this question because this request is very similar to what happens with pt-br. Can we make this possible? What's the next step? I would happily give you more info on this request if needed. This discussion is also been followed here: https://answers.launchpad.net/launchpad/+question/691515 Thank you any help you can give us!
I am a translator for the Ubuntu-pt community and I support this initiative.
