Well because Dolphin is a social-based site.... I am surprised that not a single person has ever mentioned events. Whole sites have evolved with JUST events and are flourishing, plus it is the largest revenue source for people to make money on the listings, and also draw people together. And since I have had a hand in each event system out there, I would seriously look at the implementation from Modzzz. From ticketing, to concerts, to private events, and more, it is the best system with a full grasp see more of recurring events. Anything without an events system is just a VIRTUAL system with disparate people never given a good way to connect face to face.
