I’ve enabled user interface language settings. Since we’re all being Anglophone here it won’t make a big difference, except that it determines what language your web browser is prompted to use for its built-in spellcheck.
If this is a thing you care about, it may be worth checking your settings: (User icon), (cogwheel), Preferences, Interface, Interface Language. English options are “English” (UK) and “English (United States)”.

Must be a bug … I can’t find Klingon 
Too proprietary.
Nation shall speak pish unto Nation ;- )
Thank’ee, Feral.

Coo, I didn’t realise I was American. Have now changed it. Thanks and phew!
Not to worry, Dahlink, neither did we ;- )
It used be said that the easiest way to tell a Canadian from an American was to mention to a Canadian that you couldn’t tell the difference 
I was taught always to say “Are you from Canada?” never “Are you from America?”, and that was better to ask if someone was Tasmanian than if they were Australian because an Australian wouldn’t mind, and a Tasmanian would be utterly delighted.
And never “Are you from South Africa?”.
Oi!
Can’t imagine why…
