Thank you for that info. I installed the plugin but I can’t get it to do exactly what I want. I want to restrict the writing of posts only. Each user can post to and manage one category only, but everyone can view all posts. If I give a user access to one category, then once he/she has logged in, he/she can see only posts in that category.
I need to be able to assign separate permissions for viewing and writing posts.
Any other ideas?
