I studied French at school, and did a bit of self teaching many years ago, when I was working at De Lorean. (A team of Renault engineers helped us to plan the production line for the car - I was the Chassis engineer)
André was teaching me Dutch. I think he gave up
Seriously thuough, "we" managed to translate quite a lot of the Captions and Help messages from English to Dutch, so I learned a little.
Margarida translated Flower Genie from English into Portuguese. I have to finish that exercise off, so I guess that's next! (Well, in my languistic education, of course )
I havent tried German.
However, that Dahlias (oops, Dahlie) site has some pages in English, and I had an "educated guess" on other pages, so I found what I needed.
