Multi Articles Managers or ?

[domineaux]

I would like to allow specific individuals permissions to post/edit within a specific category of Articles only.

[G6Cad]

Set the permissions for the groups you want to be able to edit them or post in them.
You have all the settings right there when you create the article.

When categories have permissions, this will be 100% possible. As of now it will, like G6 says, be possible to allow editing of all articles for a group - or just their own articles.
