Last year the IGL Fall gathering was held at the same time and place as the Paro gathering. We were invited to sit in on two of the lectures one by Horst Linke and the second by Martin Hallmann. The entire weekend was conducted in German. Peter was industrious and obtained a translation device so Helene and Peter were able to provide simultaneous translation of both presentations. The two lectures were the highlight of the weekend. I would think this session will also be in German to answer your question. I see that Horst has another presentation scheduled for this event. It would be fantastic if someone (hint, hint) were to do an abstract of his presentation and post it on this forum.
