Consider the new Social Networking subsystem

that SBRU is researching. Think in terms of the

user goal technique to identify as many use cases

as you can think of that you would like to have in

the system. SBRU is guessing you might want to

join, send messages, and so forth, but there must

be many interesting and useful things the system

could do before, during, and after the trip. Draw

a use case diagram for these use cases.
