Content Profiles allow administrators to craft custom check-in and search screens. They can perform all sorts of default metadata tips and tricks and generally craft targeted, context centric pages that help users properly apply metadata to their content.
On occasion I have been asked about how to hide the Standard Check-In and Search menus once Content Profiles have been enabled. This post explains how to construct a component to accomplish this task. You can also download this Sample Component to Hide Standard Profile Menus.
When you install this component it will prompt you for four (4) preference variables. These variables (2 for each menu) indicate if the functionality is currently enabled and what iDocScript should be executed to determine if the menu item should show or not. The default settings hide the menu from anyone without the admin role.
