A Note on Privacy

This project is built on the principle that you can participate without revealing who you are, and that applies here too. Please don't send personal information like your full name, address, or ID documents. An email address is all we need to reply to you, and we never share it.

What to Expect

The team reads every message. We reply when a reply is needed. Questions, corrections, and time-sensitive issues get priority. We don't send newsletters or marketing email from this address, and we won't add you to any list.
