If you're a use of KDE and would prefer to have the British English spelling instead of the Americanizationed English (is that a word), there are several ways to get it.
The KDE Localisation project has an en_gb team at http://www.kde.me.uk/index.php?page=kde-en-gb.
If you use KDE on FreeBSD like me, there is also a localisation tarball in the ports collection.
Now only if they had a Singlish version as well. Can you imagine it?
Salamat Datang ke KDE! Apa kabar? Program install fail. Wah lah. Hey ang moh, chicken are you?
