My b2evolution Version: Not Entered

Hi! I would like to have a login page on my website to prevetn users who are not registered from viewing the blogs. I have just installed b2evolution, and looked through the site documentation and played with the software, it appears to give you "BLOG A" screen with the option to log in, but allows full viewing of all the blogs.

Any ideas? A login page? Maybe there is a setting? Thanks for any/all help!
