Questions, corrections or ideas for the site? Send a message and I will read it.
How to reach us
Email: rusticreckoner@gmail.com. The form below reaches the same inbox.
Use the form for general questions, press or partnership enquiries and anything that does not fit the other forms. If you are reporting an error in a calculator, the Report an Issue form is faster because it lets you pick the calculator. If you want a new tool, use Suggest a Calculator.
What to expect
This is a small independent site. I read every message, but I cannot promise a reply to each one, and corrections to a calculator come first. When a report holds up, I check the source and update the page. I cannot diagnose a vehicle, say whether a job is safe to do on your car, recommend a shop or review a build. For those questions, please use the service manual, a qualified mechanic or an experienced local builder.
Before you write
Many questions are answered somewhere on the site already. How each tool works is explained on the How We Calculate page and on the tool's own page. Background and worked examples are in the guides. For a wrong number, use Report an Issue; for a new tool, use Suggest a Calculator. Use this form for anything else, including press, partnership and licensing questions.
