Hi all,

I have a calendar. The calendar has different kinds of events. Each  
event type has additional information so i think i need a new model  
for each new event type. eg: a game event has additional oponent and  
oponents colors info. Is this best solved via polymorphism where I  
create an eventable interface?

Thanks  
Stijn
