Corrections and Feedback
Quick answerFor corrections and feedback about content, write by email. This site does not offer classes, doubt-solving, counseling, or paid services, so messages asking for those cannot be answered. Please name the page and the section, and quote the line you think is wrong.
What makes a helpful correction
- The page address, for example the national income accounting page.
- The heading or question number where the problem is.
- What you believe is correct, with a source if you have one.
How corrections are handled is explained on how this site works.
