[rt-users] how to edit the reply attribution?

[Mike Jackson]

Hi,
 I can't find it anywhere. It seems to combine the logged in user and
date:

[root - Wed May 14 20:27:05 2003]:

 I want to repace the logged in username with some default text. I don't
want the requestors to be able to identify the username of the person
who is answering their request.

Thanks,
Mike
