User 'Ben' and 'mailman' are both in the Administrators group.  It is
cygwin that decides to display "None" as the file's group owner.  I
assume this is just a limitation of Cygwin.

On the Windows side (Manage: Users), I have users like this:
	Ben, member of Administrators
	mailman, member of Administrators

In /etc/group, I have:

In /etc/passwd:

So, as far as both Windows and Cygwin should be concerned, mailman _is_
in the Administrators group.

Next, I tried running bin/netlist as mailman, as you suggest.  This
gives the error:

  File "/usr/local/mailman/Mailman/Site.py", line 40, in _makedir
    os.makedirs(path, 02775)
  File "/usr/lib/python2.4/os.py", line 159, in makedirs
    mkdir(name, mode)
OSError: [Errno 13] Permission denied:

Next I tried 'chown -R mailman:Administrators /usr/local/mailman/lists'
then tried again to add the list as 'mailman', which gives a different

  File "/usr/local/mailman/Mailman/LockFile.py", line 422, in __write
    fp = open(self.__tmpfname, 'w')
IOError: [Errno 13] Permission denied:

Tried that too.  I get an web page stating "Error: You are not
authorized to create new mailing lists."

But, it won't be run as the 'mailman' user when it's invoked from
Apache, so that assumption will surely fail, right?

Yes, that's clear :)  The question remaining is, is there any hope of
getting around it :(
