How it works
- Register and confirm your details. An account is tied to a working email address so that answers reach you and stay private to your thread.
- Post your query. Choose the area it falls under, then set out the scene, the exhibits and what you have already done. The more context, the more usable the answer.
- Read the reply on your thread. Every query gets a reference you can quote, and you can ask follow-up questions on the same thread.
