Hi Kinsley
I get the feeling that American English that is more regarded as standard than British English.
Eeek!
Someone please tell me how I update the *proper* English en_GB language file. I'll do it today.
The file doesn't exist yet.
Potential solution if you volunteer for maintaining an en_GB 'translation' of Inkscape is Take a look at : http://wiki.inkscape.org/wiki/index.php/InterfaceTranslation#Interface_Trans...
It indicates where to download inkscape.pot. Once you've got this file, rename it to en_GB.po and modify it with the appropriate tool (poedit or kbabel).
A complete translation of Inkscape interface can consume a lot of time, but I guess, translating from en_US to en_GB might be faster.
Sorry, i have not a lot of time for providing you long explanations today. But the translator community will surely be able to help you (i've cc'ed the translator list).
Regards,
matiphas
