Throughout the programme, the co-hosts will use social media to highlight key issues and extend the conversation beyond the Summit. We encourage delegates to do the same, if they wish. However, we do request that all delegates consider the context in which they are working and contribute to the spirit of collaboration, exchange and respect that informs the World Summit. As a general guide: have an opinion but be polite; ask people if you want to take and/or post a photo of them or their presentation materials; and consider the sensitivity of any information being shared in sessions.
