How do you edit the contact form in Dawn?

[BuriedInWork]

I'd like to add more fields to the contact form but can't figure out:

1. How to do that.

2. Where the form responses go.

We're using the Dawn theme. Any help is appreciated!

Close. We're looking to move as much functionality off of Squarespace as possible. Here's our current contact form. Very simple: https://buriedinwork.com/contact

Great, thank you! How do I implement the change?
