Get in touch

Write to me.

One person reads everything that comes in, and that person is me. I answer most things within a few days — sometimes longer if it deserves a real reply rather than a fast one.

Goes straight to me. Nothing is added to a mailing list unless you ask.

If you found an error

A wrong citation, a broken link, a claim that does not hold. Tell me and it gets corrected and credited. This is genuinely welcome rather than politely tolerated.

If something here did not work for you

An accessibility problem is a defect, not a preference. Describe what happened and what you were using — I would rather know.

If you are in crisis

This form is not monitored, and I am not a crisis service. If you need someone now, please reach a real one.

US: call or text 988 · UK: call 116 123 · or your local emergency number.

Response times, honestly

A few days for most things. Longer if I am mid-build or the question deserves thought. If two weeks pass, send it again — it did not annoy me, it got lost.
