Dear DRUID organisers, I have presented at the DRUID conference this year in Lisbon from the 09th -13th of June. My university requires me to provide them with a participation certificate. Would you be able to provide me with such? Please excuse any inconvenience and many thanks in advance! Best wishes, Franziska Tinnefeld [http://static.unicatt.it/ext-portale/5xmille_firma_mail_2023.jpg] <https://www.unicatt.it/uc/5xmille>
