create user wizard 2 mail messages

Create user wizard allows me to send an email message to the user who does a successful registration.  This works very well:

<MailDefinition BodyFileName="~/App_Data/SignUpConfirmation.txt" Subject="Your new account at ..."></MailDefinition>

How can I send the same email message to a different address (mine) so I can be notified when a new person signs up?  Thanks
