which variable, if any, is available inside the session scope
for the logged-in user's username depends on which login framework
you are employing. it is not necessarily going to be
session.mm_username at all...
if you are employing CF7's login framework using
<cflogin> and <cfloginuser> tags, the variable holding
the username will be (again, likely, but not necessarily)
if you are employing a custom-made login framework, it is
impossible to say whihch var holds your user's username without
seeing your user authorization code... post it here and we will be
able to help.
