Question of the Day: What is an event? How can events be signaled? Describe IN YOUR OWN WORDS how sprites use events to communicate. How are events like Social Networking?

An event is something that sends a message to one thread to another. Events can be signaled by putting a when command on top of it. So  the scratch sends a message to that command on when to start or to do a certain task. Events are similar to social networking because we get the chance to send messages to one another telling each other what to do or whats going on.
