4. How to use paths of actors, their addresses, and ActorSelection to send messages to actors

6. How to use the life cycle of an actor to control the behavior of starting, shutting down and restarting an actor

• Inside WinTail Options, go to Run> General
• Select Run on external console
• Click OK
