Thank you for the additional information. That sort of thing really does help. Now we need to know what the translation into English said, and who ran the workshop, and where, and when. Don't forget to tell us what country this was in; it may all be relevant. If, for example, you live in Belgium, that might narrow down the possibilities.

I do know what you mean about subtitles, but you needn't be surprised to have found little information on the web. Someone has to put it there in the first place, after all. You have taken the first step toward doing that.
