Dear Andrej, Milena, Mina, Miroslav & Pavle I wanted to thankyou most sincerely for organising and for inviting me to present and attend your NERKA6 workshop in Kotor, Montenegro. I have to say it was the most enjoyable and enriching workshop I have attended from both a scientific and a personal perspective. The breadth of talks was such that I was exposed to material that was outside my normal field of expertise, and this made it both challenging and interesting. The extra-curricular program was also a real treat for me. The scenery, the ambience, the food, the people, and your kind and generous hospitality made it very special indeed. I send you my very warmest regards from Down Under. Yours Sincerely
