Leaderboard

Top local referrers.

The leaderboard opens once referral attribution is connected to Buttondown signups. Until then, use the invite link and weekly share prompts.

Do not publish live rankings, prize winners, private emails or sponsor-backed rewards until Buttondown attribution is verified and the editor approves the public launch.
