Write to us
Email is the only online route, and deliberately so: no form service, no third party, and a copy of your message stays in your own sent folder. Postal mail reaches our registered address.
Email addresses
All four are on this site's own domain. We publish no telephone number, no messaging-app account and no social media support channel, so a message claiming to be us on any of those is not us.
We aim to reply within five business days. We are a small publication, not a support desk, and we cannot always respond to everything.
Writing a message that gets a useful answer
There is no form on this site. Email is the only way to reach us online, which means nothing about your visit passes through a form service, a spam filter service or any other third party — and it means you keep a copy of exactly what you sent.
Never put a secret in an email
Never send us passwords, recovery phrases, private keys, seed words, one-time codes, screenshots of wallet or banking screens, or any other secret. We will never ask for them, and we cannot use them.
Email is not a confidential channel. It passes through servers you do not control and it stays in two mailboxes afterwards. Send us the question, never the credential. If you have already sent something you should not have, change it wherever it is used, then tell us so we can delete the message.
Pick the right address
The four addresses above are read by different people. Choosing the right one is the single biggest thing you can do to get a faster reply.
Include these three things
-
The page address
The full URL of the page you are writing about, copied from your address bar. It removes all guesswork about which article, and which version of it, you mean.
-
The exact sentence
If you are reporting an error, quote the sentence you believe is wrong. A paraphrase costs us a search; the sentence itself costs you one copy and paste.
-
What you think is correct, and how you know
A link to a primary source — a specification, a vendor's own documentation, a public advisory — is what lets us verify and publish a correction quickly. Without one we have to establish it ourselves before we can change anything.
How your message is handled once it arrives, and how long it is kept, is set out in our privacy policy.
