How to report something#

Use the contact page or write to [email protected]. Say which page, what you think is wrong, and if you can, where the right answer is published. A person checks the source, corrects the page if it needs correcting, and replies to you either way, normally the same working day.

The log#

Corrections are listed newest first, with the page, the date and what changed. Small edits that do not change a fact, such as a typing error or a clearer sentence, are not logged.

13 September 2026. The handbook launched in its new form, with every page rewritten against its sources. No corrections yet. The first one will appear here.
