Corrections and documentation

For corrections to any article or company profile: send the page, the claim, and the documentary evidence — a dated COA, a registry filing, an archived snapshot — to the editorial address below. Corrections meeting the editorial policy's evidence standard are processed regardless of which company they favor, and the corrected page carries a bumped modified date.

For documentation submissions (vendor COA patterns, pricing snapshots, exit notices): the same address. Submitted documents are used as evidence for updates, cited by date, and are never republished with buyer-identifying detail.

Directory and listings

The vendor directory carries data provided by the listed vendors themselves — product lists, quotes, contact numbers. Vendors requesting listing changes should send them from an address on the vendor's own domain, with the change scoped to their own entry; no ranking, placement, or endorsement is purchasable, because nothing is purchasable.

Removal requests follow the same rule: a vendor may correct or withdraw its own listing data. Third-party requests to edit another vendor's entry are declined without registry-grade proof of authority.

Everything else

Rights, technical, and general inquiries are welcome at the same address; note that the site is a personal project with a small inbox and replies are batched, typically within a week. Before writing about scope questions, the about and disclaimer pages usually answer them.

Editorial address: [email protected].

Frequently asked questions

How do I request a correction?
Email the editorial address with the page, the claim, and documentary evidence (dated COA, registry filing, archived snapshot). Corrections meeting the evidence standard are processed regardless of which company they favor.
Can vendors pay for listing changes or ranking?
No. Nothing on this site is purchasable. Vendors may correct or withdraw their own directory data, submitted from their own domain.
