DjangoEstates is a real estate application. A user can register and check all the uploaded estates for sale or rent. Also if the user becomes a broker he can upload estates for sale or for rent. Otherwise, he can follow the djangoEstates blog news and comment on different posts there. If a user is broker, he can upload estates but cannot add comments in the blog page.
