Contact
Corrections, bug reports and requests for a tool that does not exist yet are all welcome. A reported error on a calculator gets looked at: those matter more than feature requests.
Please include the URL of the page and, for a calculator, the inputs you used and the number you expected. That is usually enough to reproduce a problem in one go.
