What is worth writing about
A tool that does not work on your device — please say which browser and which device, because most hardware tools behave differently across them.
A translation that reads badly. The site is published in five editions: English, British English, Japanese, Korean and Spanish. A phrase that sounds wrong to a native speaker is something we want to know about.
A factual error in a test description or a guide.
Anything about your data. See the privacy page first — it may already answer the question.
