I have installed this fantastic plugin.
It works great for part of the things I wanted to do.
I wanted to restrict access to some of the categories in my site to selected groups of people.
It works great for that: I create the groups with option read and write restricted for the group, and then assign it to the selected categories. I DON't USE the role option in group creation (I am not sure what it does).
Thus people that is not in the corresponding groups, cannot access (read or write) posts in the corresponding categories.
And people that is in the group can access it.
If they are suscriptors, the can just read, and if they are contributors or authors, they can create new posts.
But now I have the opposite problem
I need to restrict some of the authors to write articles just in the categories that belong to a group where they are added, but not in the whole blog.
And authors that don't belong to any group, should be able to write posts every where.
How can I do this with this plugin?
