Ideally, they would create a new event type for indicating that someone is typing. When someone started typing, their client would send that event to the server, and the server would send it out to all of the other connected clients. The receiving clients would then display a message saying that the sender was typing. These details aren't really important though, since Wikia would do all the work for you.
