Setting up sub sections with their own editors I'm new to Drupal (v7.21) and hoping to use it for a site that contains several sections each run by a separate owner and their team of editors. Just wanted to ask if it would be possible and how I could go about it. The type of flow I'm looking for is:

Main Site
- Forum
- Store

  Section One
  - Blog
  - Book

  Section Two
  - Blog
  - Book


As normal the Admin would have overall control with each section having an 'owner' that can edit their sections Blog, Articles etc. The owners would also be able to give an 'editor' role to other users so they can edit content within the section.

It would be helpful if the urls for the site were:

domain.com/
domain.com/forum/
domain.com/store/

domain.com/sectionone/
domain.com/sectionone/blog/
domain.com/sectionone/book/

domain.com/sectiontwo/
domain.com/sectiontwo/blog/
domain.com/sectiontwo/book/


If I haven't included enough information please let me know. Any help would be greatly appreciated.
