Dear friends and colleagues, We regret to inform you that due to legal requirements related to COVID’19, we have to close the physical registration in Bolzano. We went well above expected success, and we thank all the people who trusted us and wanted to join this extraordinary experience. Virtual registration will stay open until June 30 and we are working hard to provide the best hybrid experience as possible Antonella De Angeli (on behalf of the SIGCHItaly21 organising committee)
