Look around a tenants' union
Larkspur House is a made-up block of 252 flats in four sections, A to D, each with seven floors of nine flats. Flat C503 is section C, floor 5, flat 3. Its tenants have been organising for a few months.
You'll see the platform as one of its members, the tenant of C503: bulletins and polls, discussions, the referendums that changed the union's constitution and policies, the roles members elected, and the emails the union sent its managing agent, with their replies.
It's read-only: you can open everything, but nothing you do is saved and no emails are sent. The people, companies and addresses are all invented. The demo is rebuilt every day.
You can also see its printable flyers and posters without entering, the ones members put up to invite their neighbours, and read the emails the platform sends.
