AnyPage lets you configure site pages at any URL you want. You can use a text editor in the admin area to create content, or if you need more flexibility, specify that the page should call a custom view.

This plugin requires you to configure it. Two pages are created during installation as examples.

Note: Pages can be registered to override paths from core and bundled plugins. This is a shoot-yourself-in-the-foot feature that you should only use if you know what you're doing!
