Create as many forms as you need. Forms are useful to collect information from your visitors. Once a form is submitted, a users account will be created in Duplie. Forms can be public (available to the world) or private where they must be a user or have certain access to submit the form. You can create forms to capture volunteer applications, surveys, or registrations.
To manage your forms, login and click Admin at the top right. Then go to Forms. There is a list of your forms. You can create forms and add as many fields as you need to your form. You can even add notifications (email someone when a person submits the form) or setup a workflow for approving the form. If you want to collect payment on forms, you will need to setup a payment processor.
