The official language for the congress is English.
All written material to be published on the web and in booklets will be in English.
Plenary lectures will be held in English.
Symposia and workshops will generally be held in English. Some symposia and workshops will be held in the Scandinavian languages and this will be announced in the programme on the website and in the written material.
The chairmen of each session will not allow for any other languages than the announced language to be spoken, but they will be prepared to facilitate language problems (translations from Scandinavian to English and vice versa) when questions are raised, or when dialogue is the main issue of the session (especially in the workshops).
