To join, you need:

• An email address at your news organisation
• A Keybase.io account with enough verifications to allow moderators be confident the person applying for the account is indeed a known journalist
• "Journalist" is a very broad term here. If you work with code or social media in a journalistic capacity for a mainstream news organisation, you pass. Ditto if you're an academic working within the journalism field.

If you qualify given the above criteria and want an account, please email aendrew [at] aendrew [dot] com with subject line "4estate membership". Please use your news organisation email account for initial sign-up, you can change it later.
