Worth writing about:

• A calculator that disagrees with your payslip or your own working.
• A tax figure that looks wrong, or a rate that has changed.
• A tool that breaks, or behaves oddly in your browser.
• A tool you need that doesn't exist yet — I'll try to build it, free.
• Anything about privacy or your data.

I read everything. I'm one person, so replies can take a few days, but corrections to a calculator get looked at first.
