Facebook, Twitter, Instagram, and other social media outlets cannot be the sole source of information.
Hence, anything related to events, practices, meetings, important conversations, and the like, must also be sent to an official listserv/email list, written in an official newsletter, and/or placed on an official website for those who are not on the social media sites. This does not include non-official posts and non-official discussions.
This policy is contained within the SCA Social Media policies found on SCA.org.
Thank you for your attention, cooperation, and understanding.
In service,
Amalie, Kingdom Webminister
