The rule of thumb about events is this: "Whoever does something to an 
object should also send the event."

That means if you modify an object, you should be sending an 
IObjectModifiedEvent. If you create an object, you should send an 
IObjectCreatedEvent, etc. As Tres already mentioned, this typically 
happens in a view. Form views already do it for you, that's why haven't 
had to do anything so far.

Note that the two container events, IObjectAddedEvent and 
IObjectRemovedEvent, are already sent by container operations and 
needn't be sent by you.
