Edit: I am no longer offering a lite free version on the WordPress plugin repository. I will only be offering the premium version and you can find instructions here how to purchase it.
This plugin will prevent logged out visitors from accessing your BuddyPress
community pages. The Lite version has a dashboard setting to allow 6
unblocked pages. I will be releasing a premium version with more
options soon so stay tuned. Until then enjoy Private Community For BP
Lite. You can get it here.
