Modules

We are looking to implement a Drupal Commons site where there are different regional groups, as well as Topic Groups.

I want to have a paid subscription service whereas users can have their own store and sell downloadable products.
Ideally to also retain a percentage of said sales.

I have been using Drupal from the beginning, however we are not so used to OG ( organic Groups )

Hi All,

Could any one please help me to know if there is any module available in Drupal 7 for creating Nested Content Types.

if fruits is a content type,the content for fruits :1.Apples,2.Oranges

When I click on Apples it should show the content for Apples : 1.Gala Apples,2.Criterion Apple

When I click on Oranges it should show the content for Oranges: 1.Navel Oranges,2.Valencia Oranges

when I click on these child content(Gala Apples,Criterion Apple,Navel Oranges,Valencia Oranges)it should open an url which is related to that content
