Guidelines

Guidelines for participants

• Update the pad with your participation details (it helps us planning lunches and breaks)

Guidelines for all speakers

• Lets make the talks short. Each topic should be presented in 15 min. at most.
• The language for the event will most probably be French (if everybody speaks French in the room), however slides and materials should be in English if possible, to ease publication
