• Corrections. If a number looks wrong, tell us the page and the figure. We check it against the source file and fix publicly — the correction note stays on the page.
• Press & researchers. Our datasets are built from public files; we're glad to share methodology details or custom cuts of the data.
• Everything else. Feedback and ideas are welcome. We read all of it, even when we can't reply to each message.
