This is for making User Stories / specs / mockups deciding on the UX for https://git.snowdrift.coop/sd/snowdrift/issues/107 (which has some notes worth referencing)
The core issue is GDPR-related. We want to have a specific action that users take to acknowledge and accept our policies, not just a soft acceptance of "by signing up, you implicitly accept". It could be a checkbox in sign-up (common) or a separate email with a link… one core point is the ability to take the action again later to accept updated policies. What should the UX for this be?
