To send story tips securely and privately: You can send email with PGP encryption using the key in this file [MVOstranderPub]. I am also listed in the PGP Public Key Server. The Electronic Frontier Foundation offers helpful instructions for setting up PGP for Mac or Windows.
By request, I can provide a cellphone number for sending me secure messages on Signal or an address, for old-fashioned snail mail.
