How to remove sub-nav menu items?

I need to remove some links that appear in the sub-navigation menus.

For example, I need to remove the guestbook link in the member view sub-nav menu.  I looked in the menu guilder, but didn't see it.

Thanks,

Bill

It's in there. Normally appears under the 3'rd item over under My Profile. Bottom item.

I deleted it from the menu builder, but the link still appears on the member page :-(
