You can switch the Users table by opening your app from your Formaloo dashboard and clicking the Change Users Table button.
Then from the list, you can choose a new table or create a new Users table from scratch.
The Users tables have some mandatory fields, like email, and some admin-only fields, like Role. The Role field allows you to create different user access levels and define which Roles have access to which pages. Following, you can see how to do this.
