If you want to communicate with a member securely I strongly suggest go off board and use end to end encryption solutions like matrix chat, otr, protonmail, pgp, smime. No bullshit email is required for registration, this also means that if you forget your password you lose access to your account permanently! As I have no way of verifying identities here, you can consider your account be gone forever.
