Restrict post or pages – How to

Hi,

I’m starting using your plugin. Very nice.
I’m wondering how to restrict/allow to members some posts or pages (not only part of the content)
I mean there’s something to do while editing the post or the page?
How can I ‘say’ wordpress to not show that post to a member?

Using another plugin it was simple: there was a list of member plans. Flagging that plans you can exclude that kind of member to access the page/post.

How I can do it with your plugin?
Thanks a lot
