We are using Drupal to create a custom content type with it's own module along with a site to support that. My boss wants to create a "viewer" user role for groups, where such a member can view the content associated with the group but not create content for that group. This would only make sense with private groups. I have looked into the existing settings for Organic Group User Roles and Permissions and there is nothing to control whether someone can create content associated with the group. Do I have to go in through the API to create this? If so, does anyone have suggestions on how we should approach this?
