Need some help modifying admin_activate.tpl

This is the first time I've had to post because so far I have been able to find the answer to every question I've had on the integramod.com forum, but I can't find this answer, so pardon me if this is the wrong place to post.
I am working on a private forum for a club. I have added required fields to the registration page of user_reallastname and user_memberlevel, and I modified the user_realname label to be First Name SO we are capturing First Name, Last Name and Member Level on registration. Registration has to be approved by the administrator. Right now the email that is sent to the administrator only has the user name. It says:
The account owned by "{USERNAME}" has been deactivated or newly created...
I would like to change it to say "First Name Last Name, Member Level has requested membership..."
I assumed that since the field for username is called username, that I could use {USER_REALNAME} etc. but that did not work. It just sends the email with blank spaces.
I'm sure there is a way to pull that information into the template, I just don't know how to do it. Could someone kindly point me in the right direction?
Thanks,
