I am building a site in Drupal, where there are 2 different types of registered users. Let us call them basic users and premium users. These could be roles, or groups, or something else.
Authorized users will be able to publish pages with simple content and comments underneath. All pages are viewable publicly, even by non registered users and so are the comments.
Only registered users should be able to post comments.
What I would like is for some pages to allow comments only from premium users. So, there would be two categories of pages. Again let us call them basic pages and premium pages.
The permissions would be as follows:
COMMENT: basic users, premium users
COMMENT: premium users
Any help/pointers would be appreciated, as I have limited experience with Drupal.
