[Mailman-Users] Changing URL

[Roy S. Rapoport]

I've got a currently-running 2.0.8 installation.  I've
installed a 2.1 instance as completely separate, but am
finding that, somehow, while
http://www.inorganic.org/mailman2/admin works, the links it
forms are of the form:
http://www.inorganic.org/mailman/admin/<list>

rather than
http://www.inorganic.org/mailman2/admin/<list>

This is despite the fact that my mm_cfg.py has:
DEFAULT_EMAIL_HOST = 'inorganic.org'
DEFAULT_URL_HOST = 'www.inorganic.org'
DEFAULT_URL_PATTERN = 'http://%s/mailman2/'

What am I missing here?
