In light of the release of Form Wizard Pro 2.6, and its capability to process custom form submission handlers, I was wondering if I could quickly build something that would send a copy of a Form Wizard Pro submission to the person completing the form (in other words, where the "To" e-mail address is not known beforehand).  

Modeling my code off of what's delineated at http://www.mojoportal.com/implementing-a-custom-form-submission-handler.aspx, here's what I came up with (in case it saves somebody a few minute's work ). Alternatively, see http://code.colostate.edu/implementing-a-custom-form-submission-email-handler.aspx for the zipped VS solution:  

class MojoFWPMailer : FormSubmissionHandlerProvider
    {
        private static readonly ILog log = LogManager.GetLogger(typeof(MojoFWPMailer));

        //Custom properties
        private string _FromEmailAddress = "YOUR_EMAIL_ADDRESS";
        private string _ToEmail;
        private string _EmailQuestionText = "EMAIL";
        private string _Subject = "Form Submission Received";
       

        public MojoFWPMailer()
        { }

        public override void FormSubmittedEventHandler(object sender, FormSubmissionEventArgs e)
        {
            if (e == null) return;
            if (e.ResponseSet == null) return;

            log.Info("MojoFWPMailerFormSubmissionHandlerProvider called");

            StringBuilder results = new StringBuilder();

            //how to get the site user if the user was authenticated
            if (e.User != null)
            {
                results.Append("submitted by user: " + e.User.Name);
                results.Append("\r\n");
            }
           
            //how to get the questions and answers

            List<WebFormQuestion> questionList = WebFormQuestion.GetByForm(e.ResponseSet.FormGuid);
            List<WebFormResponse> responses = WebFormResponse.GetByResponseSet(e.ResponseSet.Guid);

            foreach (WebFormQuestion question in questionList)
            {
                if (question.QuestionTypeId == 8) { continue; } //skip instruction block

                string response = GetResponse(e.ResponseSet.Guid, question.Guid, responses);

                //Try to extract e-mail address
                if (question.QuestionText.ToUpper().Contains(_EmailQuestionText))
                {
                    _ToEmail = response;
                }

                results.Append("\r\n" + question.QuestionText + "\r\n");
                results.Append(response);
                results.Append("\r\n");

            }

            // how to send an email with the results and file attachments
            // you could get settings from config settings if you don't want to hard code it
            // you would need references to mojoPortal.Web.dll, mojoPortal.Business.dll, and mojoPortal.Net.dll
            // to use this commented code
            string fromAddress = _FromEmailAddress;
            string emailTo = _ToEmail;
            string subject = _Subject;

            Email.Send(
                    SiteUtils.GetSmtpSettings(),
                    fromAddress,
                    string.Empty,
                    string.Empty,
                    emailTo,
                    string.Empty,
                    string.Empty,
                    subject,
                    results.ToString(),
                    false,
                    Email.PriorityNormal);

            log.Info(results.ToString());

        }

        private string GetResponse(Guid responseSetGuid, Guid questionGuid, List<WebFormResponse> responses)
        {
            foreach (WebFormResponse response in responses)
            {
                if (
                    (response.ResponseSetGuid == responseSetGuid)
                    && (response.QuestionGuid == questionGuid)
                    )
                {
                    return response.Response;
                }
            }

            return string.Empty;
        }
    }
