Dear IROWG, As mentioned during IROWG-11, in addition to the general IROWG mailing list, several subgroup mailing lists have been created to facilitate communication within specific IROWG subgroups. Currently, subgroup mailing lists are available for Climate, Innovation, NWP, and Space Weather. Each subgroup mailing list is managed independently from the general IROWG mailing list, and membership in one list does not automatically subscribe you to another. The subgroup leads serve as the moderators of their respective mailing lists and will manage how each list is used to support communication within the subgroup. If you participate in an IROWG subgroup, you are encouraged to subscribe to the relevant subgroup mailing list. Please visit https://lists.irowg.org <https://lists.irowg.org/?utm_source=chatgpt.com> to subscribe, manage your subscriptions, and access the mailing list archives. Instructions for subscribing to and managing the mailing lists are available on the IROWG Mailing List <https://irowg.org/further-information/mailing-list/> webpage. Thanks, Hui IROWG co-chair
