I have multiple content types like news, publications, etc and I will like to link them to pages on my site. So when a user posts a news item on a specific page, it only shows up on that page only. Also I will want users to be able to edit content on only pages they have been assigned to. Eg. A user will only be allowed to add news to pages they have rights to. I was considering using groups for this, but I know more suggestions will be helpful.
Many thanks Isacc
