I am looking to restrict a specific post for registered members only. (the same way you could choose a post to be private -> to choose it to be "members only")
And have found no way to do so (at least not for the new versions of WP).
The closest thing I found was "wp-members". which is a nice plugin, but it restricts the whole website, and doesn't allow looking a specific post.
The other plugins around are too old, and not compatible, or not downloadeble.
Any one interested in allowing such extension for WP ?
