Hello, I am writing to kindly request a confirmation letter regarding my role as a reviewer for the DRUID Conferences in 2018, 2019, 2020, and 2021. During each of these years, I reviewed three papers, contributing to a total of 12 reviews. As I currently do not have documentation of my involvement, I would greatly appreciate it if you could provide me with a letter confirming my participation as a reviewer for these conferences, including the number of papers reviewed each year (3) and in total (12). Thank you in advance for your assistance. Your confirmation would be of great help to me, and I look forward to your response. Best Regards, *Nazanin*
