That's a great link Roger and I must admit that I had been told that Catalan was an official  EU language.  It was probably wishful thinking!

There are some interesting statistics here: http://ec.europa.eu/education/languages/archive/languages/langmin/euromosaic/es51_en.html#13

Proficiency has increased rapidly since 1975. Comprehension increased from 81% in 1981 to 94% in 1991, spoken ability from 64% (1986) to 68% (1991), reading ability from 61% to 68% and writing ability from 32% to 40%. Levels of language proficiency are, moreover, highest among young people aged between 10 and 19. According to a recent study, 74% of adults can speak Catalan, 65% can read it and 41% can write it. Catalan is the main language of 50% of those surveyed, whereas Spanish is the main language of 49%. Some 10% of the people who can currently speak Catalan spoke Spanish as their habitual language in infancy, but have subsequently adopted Catalan as their language of habitual use. Most Catalan speakers use the language in all daily situations. According to another source, 54% of adults use Catalan at home, 11% use Catalan and Spanish and 34% use Spanish.

"By the way, if anything legal comes along, you do have the right to insist that the form you sign is written in English by an approved organisation. Whether or not the trained monkey who gives you the form will comply with this or whether you get any joy out of their boss, is another thing completely."
Is that really true?  Because our catalan friends who have helped us translate official documents have trouble themselves understanding official 'jargon'. If we could get letters in English that would be a small miracle  8-)
