Basically you declare:
public delegate void SimpleDelegate();
public event SimpleDelegate TerribleEvent;
protected void OnTerribleEvent()
if (TerribleEvent != null)
and you use OnTerribleEvent to fire the event;
You connect to the event from another class by:
FooInstance.TerribleEvent += MyMethodMatchingSimpleDelegateSignature();
