The instructions to add Profile book to user menu refer to an expanded menu tree. The list that shows up is not expandable as referenced below in the manual.
To add the CB Profile item to the User Menu we must take the following steps:
Select Menus User Menu from your Joomla 1.5.X website administration panel
Select the New Item button and you will see the Select Menu Item Type panel with a tree structure of items.
Choose Community Builder from the Internal Link tree item to further open the tree and reveal addition Community Builder items as illustrated in Figure 7
Select the User Profile (mandatory!) item from the expanded list
Been a while since I used joomla 1.0x. Since I can see from your compoennt list that you are just starting to build the site. Is there a reason you are not going with the latest 1.5.x? Some experts have suggested they are skipping J! 1.5 completely, even for new sites so I'm not criticizing.
What version of CB or you using?
Can you not just select the Community Builder link from the list you are showing?
