Is it possible to restrict a user to being able to post (write) to one category only?
What I want to do is use WordPress as a news fed site for an online mall. Each user on the site is a store owner in the mall, and I wanted to make it so that when they log in and write a post, the post will be written to 'their' category.
For instance, Mary owns 'A Dolls World" which is a store in the mall. So I create a category called "A Dolls World"
When Mary logs in and goes to write a post, the way it is now is that she can select which category she will post in. But as many new users are likely to do, she may forget to check 'her' category and post to the default category instead. I would like to make it so that she can only post in her own category.
Is this possible?
And, BTW, perhaps there's a better way of doing this altogether. Allow me, if you will, to ask this:
My idea is to create a category for each store in my mall and allow store owners to have their own news feed.
My limited experience with WordPress allowed me only one idea on how to do this; by setting up a category for each store owner.
This way, every time a store owner posts a news item, (and assuming the user put the item in their own category, the item would show up on the front page as well as in their category. Fans of that user could subscribe to that particular category, which would keep them updated on anything new in that users store.
The news item would also show up on the front page, allowing fans of the entire mall to subscribe to the entire site rather than one or two individual stores.
Is this one-category-per-store the best way to accomplish this, or am I missing some bigger picture.
