Well the article does not talk about what I said and neither do the plugins listed achieve it. Quote from your article:
Contributers are authors on probation. They can write their own posts and edit them before they are published. When a contributer is done writing and editing their post they can submit it for review. At this point an Editor or Administrator would need to publish the post before it appears on the blog. Once published the contributer looses all privileges with regards to the published post. Contributers cannot manage their own comments. Like Authors, contributers are able to see the titles of all posts including scheduled ones. Contributors can see all comments, including unmoderated ones, but cannot edit any of them.
Just to make it clear again:
Like Authors, contributers are able to see the titles of all posts including scheduled ones. Contributors can see all comments, including unmoderated ones, but cannot edit any of them.
I do not want them to see title of all posts. In the admin area they should only see titles of posts which belong to them. They also not be able to see unmoderated comments.
The article/ plugin do not help in this.
