Corrections and contact

This is a reading site, so there is no contact form, email address or phone number here. That is deliberate: many readers are students, and we would rather not collect anyone's details.

We re-read the notes each school term and correct anything that has gone out of date, such as a renamed editor, a retired kit or a changed link. When a note changes in a way that matters, we say so at the bottom of that note.

If you came here looking for a robotics competition, see the archive page: we are not a competition and cannot help with entries or events.
