How to hide the forum for unregistered users
 

Hi there...

My forum is www.afkarona.com/vb

the unregistered users can still see the menu and some information that I would like to hide.

To raised my issue to the point, I want to make my forum look like this one:

http://www.multaqana.org/vb

As you can see, the unregistered users can not even look inside the forum or any its' parts.

Please help
