You can add some limited functionality to pages by adding a Pods shortcode. For example, over at https://govintranet.helpfulclients.com/task/add-an-item-to-the-jargon-buster/ this task page contains a Pods shortcode to allow anyone to add a new item to the jargonbuster. You’ll find a button on the main content edit toorbar to add Pods.
There are various Wiki plugins that you can use but they mostly rely on user accounts.
