dear john and all, thank you for your informations and the feedback resp. think tank. it was a great pleasure for me to participate these fruitful days! just a consideration for the date of the next congress: the place south-turkey is a wonderful idea, i have never been before at that place of earth. but: i tried to look for bookings with several airlines - as it is the week before eastern, it is difficult to get tickets for the right days - and to low prices! so i suspect, this situation will get worse soon and will prevent some people to coming there ! ? could this be a point to better take a "neutral" time - apart from time of vacancies ? dörte
