You can create custom forms, surveys to collect information from your visitors. You can also restrict forms to certain users or groups, and even make them public to the world. To manage your forms, login and click 'Admin' at the top right. Then Content >> 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.
