10 writers cannot keep 734 pages perfectly current on their own. If you find something wrong, telling us is genuinely useful.
The way to reach us is [email protected]. We read every message.
- A correction. Tell us the page and what is wrong. This is the mail we act on fastest.
- A product we have missed. Useful, though we cannot promise to add it.
- Press, licensing or anything commercial. Same address.
Every message is read. Not every message gets an answer — corrections do.
Things to take elsewhere
We do not sell anything, so we have no part in your order. For a delivery, a refund or a return, that is Amazon. For a fault, a warranty claim or a manual, that is the manufacturer. We have no access to either and no way to look up an order.
