Collaborate mode allows you to convert Project Books to multi-user format, check in and check out files, lock and unlock Project Books, and access the Administrate function to manage users and servers (for system administrators only).
The following options are available:
If the Project Book you are working with has not been converted to collaborate mode, the File menu option reads Convert to Collaborate.
If the Project Book has been converted to collaboration mode, the File menu option reads Collaborate, and contains a submenu with several additional options.
