I have created some custom fields for my registration page thanks to the fine tutorials offered here. What I need to do now is edit the email template:

EMAIL_USER_REGISTRATION_ADMINISTRATOR_BODY.Text

Its default code includes the following:

Date: [Date:Current]
First Name: [Profile:FirstName]
Last Name: [Profile:LastName]
Unit: [Profile:Unit]
Street: [Profile:Street]
City: [Profile:City]
Region: [Profile:Region]
Country: [Profile:Country]
Postal Code: [Profile:PostalCode]
Telephone: [Profile:Telephone]
Email: [Membership:Email]

I notice from this that Profile is paired with several field names and then Membership is paired with the email field name. I tried using both of these and neither worked. How am I to determine what the pairing is for the new fields I have created?
