We've added many new options for processing form submissions. You can now:

• Access all form fields when defining notification messages to go to the person who submitted the form, and to the admin for notification
• Specify the recipient of the admin notification message through hidden fields
• Have the reply-to address for the admin notification be the email address of the person who submitted the form
• Specify a fixed reply-to address for the admin notification to maximize deliverability
• Choose to have form submissions be moderated or not

We've updated the existing support article, Creating Forms for User Submissions, and we've added a new article that explains all the notification options, Customizing Email Notification for Form Submissions.
