How do we share and work together across our campus network if we're not on the same LAN?
Bonjour only works within your own respective LANs (subnet) even though you're working from inside the same campus or company network. You may be able to automatically share with a colleague in the same physical office or meeting room, but not to a colleague in a different physical office or building, without providing them your computer's address yourself. Give the other person your computer's local IP address and ask them to manually enter it in the Open Shared Notebook panel. Consult the Sharing Made Simple documentation for additional help.
