title: Require a new page in a wiki to use a template
body: <p>Let's say I want to make a wiki of addresses, using a <code>Template:Address</code>. How do I make it so that, if someone goes to a new page &mdash; e.g. <code>myaddresswiki.com/John_Smith</code> &mdash; to add their address, it automatically includes my <code>Template:Address</code> in the page?</p>
