## How to contact

- Use the [contact form](https://www.jdeen.com/contact). In browsers that support WebMCP, the page also registers a `send_message` tool, so a browser agent can send the message through a structured interface instead of filling in the form.
- A message may need to be confirmed before it is delivered: a link is emailed to the sender's address, and the message is delivered once the sender opens it and presses the confirm button on that page. Give an email address the sender reads.
