private posts – available to subscribers

Hi all – I have a unique issue here.

I have a clients site that has 4 main categories, and 4 sub cats to each main. I need to be able to post private posts in any of them, where subscribers and admins (those are the only two roles in use) can read them, but those not logged in cannot. So far, when I’ve made private posts, they can only be seen by the person who’s posted them when viewing the site logged in. When logged in as a subscriber, they do not appear.

I’ve tried Owen’s role mgr plugin, thinking it would allow me to set subscribers to read private posts, but it doesn’t…

any ideas on this? it’s pretty urgent… 🙁
