My request to ask for TZ and LANG was a bit selfish, because i would like to use it for the calendar app. Whenever selecting a contact as an attendee, the invitation email should automatically use the contacts language and also show the time in the attendees' local timezone.

As i already mentioned at Nc conf, i would just offer the same list of languages we do in the server.
If we allow the user to enter a language, they will most likely enter stuff like "Deutsch" or "Français", which will be a tremendous pain for us to parse and map to the list of languages that we ship.

Offering that list of languages will provide a big advantage and i personally don't see the need to offer the user to enter every silly dialect that's spoken in whatever village with 5 people living there.

Okay :)
Shall I auto match the first prefix of a language tag?

If it's set to fr-ca-xx-xxx-x-x-x, I match with fr?
But if you change it would just set 'fr' !

[georgehrke]

Sounds like a good plan to me :)

@tcitworld we should maybe update our server list with transifex data?

[skjnldsv]

I don't get your message @tcitworld :p

[skjnldsv]

Done @georgehrke :)
I need to create a model for each rfc object so I can document and be a little more clean, but that will do for now!

associated matchings:

fr			=> fr
fr-fr		=> fr-fr
fr_fr		=> fr-fr
fr-fr-*		=> fr

I don't get your message @tcitworld :p

My bad, didn't get a good look at the Transifex file.
