Two mailboxes, on purpose
Contact the daily investing game guide
Write to [email protected] about anything published on this site. For a receipt, a sign-in, or a Supporter charge on the daily investing game, use the address printed on erstwhile.io: [email protected].
What to include
Send the page path, the sentence you think is wrong, and the public URL that contradicts it. A screenshot of a public page helps. A screenshot of today’s unrevealed puzzle does not: I will not post holdings or a hidden year, so please don’t send those as the correction.
I read corrections against the same sources listed at the bottom of the page. If you are the person who makes the game and you want a line changed, say so in the mail. I still need a public page I can cite.
What this mailbox is not
It does not sell Supporter plans, reset a streak, or restore a Google sign-in. Those sit with the game. It also does not take guest posts that exist to drop a link. A useful note names a fact and a source.
Questions
How fast is a reply?
There is no published service level. Editorial mail is read by the person who updates the pages. A game outage is faster through [email protected].
