What I want to do is have drill down geographical hierarchies,
Continent (Root Page) => Continent (Child page of root) => Country (Child page of continent) => State (Child of Country Page) .
At the state level offer a blog registration that can be set up at the community level ie North America => United States => New Jersey Blog title "Absecon-Island-NJ" or "Ocean-City-NJ". I then want a blog roll associated with the state to show what blogs are available for example in NJ. Can a blog have sub blogs? ie NJ Blog, Ocean-City-NJ child blog?
What would you recommend as the best way to do this. Just because I have pages set up right now, I can change?
