Am I being really stoopid here. How does one get the in built contact form to display?

Plugin is activated and I am just using the the default theme while I test out ZP for the first time.

TIA

The form is not really build it. It's an optional plugin that as most need that you add their function to your theme itself (as stated on the plugin backend page on top). See the theming tutorial for custom pages. Create on name "contact.php" for example. Then add the printContactForm() function to that page and create a link to it.

The nightly builds however have an optionally contact page by default.
