One way to become involved as a contributor or a supporter of the Vital Syllabus project is to use the #education channel in the London Futurists slack. That channel has been created specifically to support the Vital Syllabus project.
If you’re not already a member of that slack application, you can use this invitation link (link updated 4th March 2022) to join it. (You can ignore Slack’s comment “We suggest using the email account you use for work”. Instead, use any email address that you like.)
