What you need
Before
Get a large table, longer than you might think you need. That's the trick: the empty chairs are the mission. Two borrowed folding tables pushed together under string lights do the same work.
Set a number that scares you a little. Sarah picked 500 in a year. Yours might be 50. Write it down and tell people, because a public goal turns dinners into a project folks want to join.
Post the invitation where strangers will see it, not just friends. Set up the dinner in Plurality, share the link on the neighborhood networks, and make it a potluck. Print your poster and share it widely in the neighborhood. Use the Needs tab to invite folks to contribute something, maybe a dessert or a drink. Folks trust a gathering more when they're asked to bring something.
During
Do names first. Go around with names and how long you've lived on the street, and expect the answers to shock people. Ten years and never meeting is normal. Folks can also use the “Introduce yourself” tool in Plurality and tell a little bit of their story there.
Host less, sit more. Fill your own chair, keep introductions moving between courses, and let the long table do what long tables do: seat people next to someone they didn't choose.
After
Take a photo of the full table and invite folks to record any other Moments.Then ask a guest to co-host the next one. When somebody says they wish their street had this, help them get a table of their own.
