A guide shows the date of its newest approved row. An edit alone does not move that date. David shares the guides with his co-founder, [Clarence Cheang](https://fortitude21.com/clarence-cheang). Our [editorial policy](https://fortitude21.com/editorial-policy) sets out what the guides cite and how to report an error. Page updated 7 November 2026
