Tell me
One person reads this mail, so a reply takes a day or two rather than an hour. There is no form. Email is simpler for both of us.
The address is assembled in your browser rather than written into the page, which keeps it away from the crawlers that harvest addresses. With JavaScript off it will not appear.
A page got something wrong
A step that does not work as written, an age band that is off, a claim you know from experience to be untrue. Send the page address and what went wrong. It will be corrected or the page taken down. This is the mail I most want.

A pursuit that should be here
The list is short on purpose and grows where there is something to say. If there is a thing you did with a kid that taught something specific, and it is not on the site, say what it taught. That is the whole test.

Your first attempt went differently
The pages describe a first session and where it usually goes wrong. If yours went wrong somewhere else, or went right for a reason the page missed, I would like to know. It is how the pages get better.

Before you write
Please do not send photographs of children, and do not include a child’s name. I do not need either to fix a page, and Show Them Once never publishes them. How the site handles data is in the privacy policy; the short version is that it collects almost none.
