They are installed similarly to when:disconnected observers as follows:
  
 +<code>
 when: messenger takenOffline: { when: messenger takenOffline: {
   system.println("Buddy offline: " + name);   system.println("Buddy offline: " + name);
   //clean certain resources associated to the buddy   //clean certain resources associated to the buddy
 }; };
 +</code>
  
 The construct takes as parameter a far reference and a block of code that is executed when the taken offline event is notified to the virtual machine. ''when:takenOffline'' can be considered as a special kind of ''when:disconnected'' observers which are triggered only in case of "logical" disconnection, but not in cases of network disconnections. The construct takes as parameter a far reference and a block of code that is executed when the taken offline event is notified to the virtual machine.
