With Pinax .9 from nov. 1 2011
When starting a new private_beta project I had to make a couple of changes to the settings.py file to get things working properly:
Add to the AUTHENTICATED_EXEMPT_URLS variable r"^/admin/", r"^/about/",
I think it would be nice if settings.py also included a line for "DEFAULT_FROM_EMAIL" with a comment suggesting you update it.
