Django has several official mailing lists on Google Groups that are open to anyone.
This is the right place if you are looking to ask any question regarding the installation, usage, or debugging of Django.
If it's the first time you send an email to this list, your email must be accepted first so don't worry if your message does not appear instantly.

Before asking a question about how to contribute, read Django へのコントリビュート. Many frequently asked questions are answered there.
