The digest you quoted had discussions between people from Germany, Norway, the Czech Republic, amongst others. I personally don't speak Spanish, but can understand simple French, German, Latin and Welsh. Others may have different language skills. I find Yahoo's "Babelfish" useful for rough translation. Google also provides a similar service. http://translate.google.com/ -- Paul Martin <pm at nowster.me.uk>
