How the sign-off works

Each review is a row in our review log: the date, the guide, what the review covered and the co-founder who approved it. A guide shows the date of its newest approved row. An edit alone does not move that date.

Clarence shares the guides with his co-founder, David Guru. Our editorial policy sets out what the guides cite and how to report an error.
