How do I add a new page?
From the admin area, go to Pages > Add New. Give it a title, write the content, and publish it when it's ready.
Can I change how the site looks?
Yes — go to Settings > Design. Colors, fonts and a few other choices can all be changed there without writing any code.
What happens to messages sent through the contact form?
They show up under Messages in the admin area, and (if mail is set up) also arrive by e-mail.
