I'm a bit puzzled by the fact that the English language file is described as UK English, but is full of American spellings - e.g. optimize, favorite etc.  Plus the fact that there is no US English file.

For my own purposes I have created a local UK language file of overrides to the distributed UK language file.  I would be happy to upload it if there's a mechanism for that, and somebody to moderate it.

It's not that the existing file is wrong, just that to a native English speaker, it sounds "foreign".

Foe example, I took some time to realise that "caddie" was being used in the sense of "tea-caddy" - being a container or device for carrying stuff. It is a noun almost completely forgotten in modern English - caddy as a noun and a verb refers almost exclusively to the chap who carries your golf clubs, but not the thing he carries them in.

In my file I have changed "caddie" to "bundle", "tag" to "keyword", "*ize*" to "*ise*", and translated  the French-sounding phrases to English-sounding phrases where I could be clear as to the context:

e.g. "albums added in the database" is "albums added to the database" and so on.

I'm very new to this software, and hoping to be helpful, so I apologise if I speak out of turn.
