This is really easy!
Log in as administrator, click on Create information page, then add a title, body text and images, then Save
Your new page will automatically appear under Information on the menu (You may have a similar menu item e.g. Info A-Z)
What if you want that page in a different place in your website menu system? No problem - just email email@example.com, telling us which page you want moved and where in the menu, and we'll do the rest!
