Create posts that will only be displayed (and listed in search) for logged in members. Just add the special category Members Only to any post not to be shared publicly. Includes Members Only sidebar widget and Site News widget (all posts not in Members Only category).
There are also members_only and site_news shortcodes for listing headlines on a page or post.
This functionality was originally implemented as part of RSVPMaker for Toastmasters but could be useful for any member-oriented website.

Simply tick the checkbox “Show this to logged in visitors only” This works on a per post / per page basis. Not yet enabeled for custom post types.
You do not need to insert custom functions or shortcodes. You do not need to change theme template files. 
This plugin works by filtering WordPress core functions.
If you “hide” a parent page, the children will be hidden in the menu as well.
Technically the filters are modifying the query or the result of databse calls on standard WP features: wp_get_nav, wp_list_pages, $posts, previous_post, next_post. 
When ticking the checkbox, the plugin saves a key/value pair in the postmeta database table. 
When uninstalling the plugin, the entrys to the postmeta table are deleted.
Suggestions, Questions and feedback are welcome.

Secret Content

Easily mark any post or a page as "for logged in members only", hiding it from public view! (not for custom post types).
