In the sidebar is a menu that can only be seen by members

In this menu we can add menu items for members-only. They can link to anything you like. I have added some examples for now.

This is an article that can only be seen by members

In here we can add content for members-only. We can also set ts up so you can add multiple articles to a category, where the category is members-only. That way you can have a space to add content over time without having to remember to set each item to member-only.
