Dear all, the first day of preconference is ending, we hope that you had a good and productive time. Just a few organizational things for the next days: 1) If you lost something or forget it into a room and then you found the room closed, go to the registration space and you will likely find it here; 2) except for one room, all the spaces close at 18: please remember this if you leave your things somewhere; 3) please cooperate in keeping the spaces clean and tidy. The volunteers are not your waiters and waitresses: if you drink a glass of water, throw away the glass when you are finished; if you eat a snack, throw away the package. Don't leave your rubbish around expecting that someone will pick it up. Someone will, but it is not fair. Have a great Wikimania! Ginevra Wikimania 2016 team
