I'd like to have some of the blogs on my site visible only to authenticated users. I don't care if WPMU knows or not, just that the content is only available with a valid username and password.
I've been doing this with regular wordpress by using basic authentication through Apache, then allowing people to create WP logins if they wish to comment. I don't think I can do that with WPMU since all the virtual servers hit the same real directory.
What can I do?
