here is my Register action</p>

<pre><code>[HttpPost]
    [AllowAnonymous]
    [CaptchaValidation("CaptchaCode", "registerCaptcha", "Wrong captcha!")]
    public ActionResult Register(RegisterModel model)
    {
        if (ModelState.IsValid)
        {
            MembershipCreateStatus createStatus;
            Membership.CreateUser(model.UserName, model.Password, model.Email, null, null, false, null, out createStatus);
            if (createStatus == MembershipCreateStatus.Success)
            {
                MailHelper.SendConfirmationEmail(model.UserName);
                return RedirectToAction("Confirmation", "User");
            }
            else
            {
                ModelState.AddModelError("", "Failed!");
            }
        }
        return View(model);

    }

    [Required(ErrorMessage = "Do not Skip this")]
    public string UserName { set; get; }
    [StringLength(500, MinimumLength = 6, ErrorMessage = "Atleast 6 characters in passwords")]
    [Required(ErrorMessage = "Do not Skip this")]
    public string Password { set; get; }
    [Compare("Password", ErrorMessage = "Wrong confirm passwords")]
    [Required(ErrorMessage = "Do not skip this")]
    public string ConfirmPassword { set; get; }
    public string Name { set; get; }
    public string Address { set; get; }
    [RegularExpression(@"\A(?:[a-z0-9!#$%&amp;'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&amp;'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?)\Z", ErrorMessage = "This is not an email")]
    public string Email { set; get; }
