Ahhh, after heavy digging of the internet and gazing at example app "django-registration" I discovered that I have missed one thing - I didn't include "polls" in INSTALLED_APPS. After adding it I finally got "Polls" in the Django admin.
But anyway, thank you for trying to help me =) Seems like that my problem is solved now and I'm ready to meet next ones =) -- You received this message because you are subscribed to the Google Groups "Django users" group.
