Forms give your visitors a way to send you a message through your website using only their browser. The most common use for a form is a simple contact form to send an email. But since a form can request (or require) that specific questions be answered, you might use a form instead of an email link so you can ask your visitors to provide you with specific information.
You may create one form or multiple forms, adding them to your site where you need them. Forms may be added into the content of a WordPress page, or they may be added to a ProPhoto template as a widget.
