Hello,
- To add pages (Home, About, Links,...) and news, you must install the plugin Zenpage and then you can add pages or news via the zenphoto editor.
- To create a home page, the relevant page should not be published (case "published" unchecked) and the page must be selected in the "home" theme option (under Options/Theme)
- To add Contact, you have to enable contact_form in admin/plugin and configure it
there is many options that I invite you to explore (options / theme) to configure the theme as you like.
