It is essential that each satellite operator establish 2-way communications channels to the user community to provide general and specific information, to allow users to make information inquiries and provide other feedback during the preparations phase and to provide routine user support starting in the commissioning phase. Such communication should include e-mail list servers, dedicated User Notification Services, Wikis and other web-based 2-way communication mechanisms, providing support for inquiries and feedback from individual users, but also capitalize on Regional satellite user coordination mechanisms (such as the Coordination Group on Satellite Data Requirements for Region III and IV; RAIDEG), regional user conferences (such as the Asia-Oceania Meteorological Satellite Users Conference) and training events (such as the GOES-R Event Week). .
