I'm sorry but a search didn't provide a direct answer. I'm thinking the navigation.php needs to be modified but maybe there is an easier way.
I want to add a navigation item and change the name of one of the menu items.
1. Forums name changed to "Group Forums"
2. Add link that now sits above menu to within the menu. Please see http://www.appleipadbuzz.com and you'll see community discussions ... that should be in menu ...
