Contact

Email is the only reliable channel, and the one we actually read.

What gets a reply

• A specific error in a specific entry. Send the link and quote the sentence you doubt.
• A parts substitute. If you found a local equivalent that works and is not in the list, the model and the region are both useful to us.
• Republishing and citation. Tell us the use, the platform, and whether the text will be altered.

Response time

Usually within two to four working days. For corrections we reply once the entry has been updated.

What we do not accept

No paid product placements, no sponsored posts, and nothing that requires us to change a conclusion.
