Dear Members of WG12, At the IDA Board meeting on 4 March 2025, we discussed the structure of the IDA Working Groups and ways to ensure transparency. One suggestion was to publish the names of Working Group members on the IDA website. The purpose of this is to help each chair know who is in their group and to ensure that all members receive important updates and information. Coordination is key! If you do not wish your name to appear online, please let me know by the end of today. I will update the webpage later today. Best regards, Mai Med venlig hilsen/ Best regards, Mai Korsbæk, IDA Centre Manager, cand.mag.
