Hide some menu links from non-registered viewers

Hello

I’m looking for a way to hide some of the menu links for non-registered viewers, so that you have to login before you can see the specific link in the menu.
You can say that it is a “only member area”.

I have already installed a plugin called WP-members so I can hide posts or pages from viewers that are not logged in, but the link in the menu is still there. Anyone knows of a plugin or modification that can hide it?

I’m using Twenty-ten if it has any saying. I’m rather new to wordpress and PHP, so I hope you can help me ??
