This board reloads itself every 10 seconds. Readers on northfield.example and harlowcapital.example are ours, so the board is never empty — every other row is a real person. Real emails are masked here because this page is public. On your own board they are not.
Now do it with your own deck. Drop the PDF, copy the link, send it. Your board looks like the one above, with real emails and nothing masked.
