Corrections are the most useful thing you can send. Anything with a citation gets checked and, if it holds up, fixed — with credit if you want it.
A mistake in the material, a question about the app, a request for reduced pricing, or a source we should be reading and aren't. Anything else is welcome too — these are just the ones that get the fastest and most useful replies.
Written down so you can hold us to it. A study app that quietly ignores corrections is just a blog with a subscription.
By a person, not a triage queue. Corrections about the material go to whoever wrote that reading.
Against the source you cite and against the ones we used. If the two disagree, that disagreement is usually itself worth adding to the reading.
Or it gets a reply explaining why not. "We disagree" is a legitimate outcome; silence is not.
Named in the reading's revision note if you want to be, anonymous if you don't. Your call, and we ask before publishing a name.
