I create a DNN profile programtically and then send out a verification email, but the verification code and other details are blank (see below). 

Email content is below (I've changed the url)

Portal Website Address http://www.webaddress.com/
> Username:
> Password:
> Verification Code:
>
> You may use the following link to complete your verified registration:
>
> http://www.webaddress.com/default.aspx?ctl=Login&username=p4at1%40sketchbookfilms.com&verificationcode=

The code being used to create the profile is as follows: 

var oUser = new UserInfo();

oUser.PortalID = PortalId;

oUser.Membership.Username = txtEmail.Text;

oUser.Username = txtEmail.Text;

oUser.DisplayName = txtFirstName.Text + " " + txtLastName.Text;

oUser.Profile.FirstName = txtFirstName.Text;

oUser.FirstName = txtFirstName.Text;

oUser.LastName = txtLastName.Text;

oUser.Profile.LastName = txtLastName.Text;

oUser.Email = txtEmail.Text;

oUser.Membership.Email = txtEmail.Text;

oUser.Membership.Approved = false;

oUser.Membership.Password = txtPassword.Text;

UserCreateStatus createstatus = UserController.CreateUser(ref oUser);

But for some reason I sometimes get blank details in the email.
