I use BuddyPress, which is terrific for managing a multi-user site, but a bit of a pain when it comes to adding in non BP components to a menu, or direct linking to BP components such as specific docs. While the display of actual BP components is automatically conditional based on logged in/out, it didn't give me a way to resolve this for anything else. The "Nav Menu Roles" plug-in not only fixed this instantly, it was super-easy to install, and required NO configuration. It's options simply showed up automatically as part of the native menu configuration options in Dashboard -> Appearance -> Menus when I select/add menu options. What a terrific plug-in. As her web site suggests, the plug-in's author, Kathy, really is awesome :D Thanks a bunch for sparing me even more gray hairs than I've already earned trying to solve this.
