[Mailman-Users] customize list administrator mail

[Saurav Pathak]

Hi:

For a list that requires both confirmation and approval for
subscription, I would like to customize a message for the 
subscriber once he has confirmed and awaiting administrator 
approval.  Where do I customize the message?

My initial guess was the file ~mailman/templates/en/approve.txt but
that turned out to be wrong.  Please help.

Mailman 2.1.1
Redhat 9

Thanks,
Saurav
