You'll get answers to your questions on the django-users email list, <django-d...@googlegroups.com> - the web interface is <https://groups.google.com/forum/#!forum/django-users>.

The list you've posted to is django-developers, an email list is for the discussion of the development of Django itself.

You might also find helpful the #django IRC channel on irc.freenode.net.

I hope that helps,

Daniele
