We'll create fresh WordPress site with Private BuddyPress installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Protect your BuddyPress Installation from strangers. Only registered users will be allowed to view the installation and all other users will be redirected to the login page. Users attempting to view blog content via RSS are also authenticated via HTTP Auth.
You can exclude the registration, the homepage and blog pages (e.g. posts, archives and non-buddypress pages) from protection. In combination with the plugin ‘Invitation Code Checker’ your installation stays private but the registration is for users with a special password open.
The plugin includes a German and Hebrew (thanks to gstupp) translation.
