Need a plugin (addon, widget etc.) to make a posts or pages visible or invisible to certain users. For example:
- sort users by creating a groups (not just right-based categories) and specifying a categories and tags, to which they have or have not access to read or write.
- make a post or page (either single or all in the blog) visible only to registered users.
- make a post or page (either single or all in the blog) visible only to certain users or user groups - or to all users/categories, except some of them.
Any help is appreciated.
