Even in these latter days, if you say we have six active members left, I'd say that those six would break down to two Brits, two Canadians, an American, and a non-native-English European.
(Those are very unscientific statistics and should absolutely not be scrutinised, but ANOTHER of the strengths of this site--and strength of 2000-era forums at their best in general--was that it was and is truly international.)
Of course, as Tolkien fans, I daresay we're slightly biased in favour of British spellings in general--or, as I call them, Canadian spellings.
