- The page labels its email signup “Preview mode” and says the MailerLite connection is not active.
Field notes
The opening file includes a sample Western Union telegram reporting the missing miners and requesting a marshal. The page also gives a fictional backstory for Marshal Silas Vance, whose final report was never filed. A fiction disclaimer is visible; the signup form itself says its mailing service is still in preview mode.
