Contact the desk
Corrections first: if a guide misstates how a bill, a contract or a renewal works, we want to know, and the fix will be recorded on the corrections page.
The desk does not yet operate a public mailbox. A contact address will be published on this page as soon as one is live; until then, this page is the honest position - we would rather say that plainly than print an address nobody reads. When the mailbox opens, this page will carry it and the guides' checking dates will show the change.
What to send when it opens
The guide's address, the claim you are reading differently, and the source you are reading it from. Messages that cite a source get answered first, because they can be checked fastest. Please do not send personal financial details; the desk cannot advise on individual situations and does not need your numbers to fix a guide.
