I just updated one of my more popular plugins, WordPress Access Control. The newest version, 3.0, includes an admin options interface for setting various default values and behaviours. I’ve also added compatibility for posts and custom post types (Directly from the admin interface), and fixed issues with searching. You can now decide to not show members only pages in search results, show only a title with a custom message instead of an excerpt, or show the title and excerpt but require a login for the full article.
In addition to the above changes I added two shortcodes, and for restricting specific content on a page to either members or non-members. Enjoy!
