I think the translation isn't being used - many languages are listed in the options but there is no English-US option listed (which seems very unlikely, especially as there is a Canadian English option).
In addition the text of the English-GB version is in US English, and English-GB is identified with the stars and stripes. -- [gcompris] English-GB is English-US and uses the US flag https://launchpad.net/bugs/62764 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
