The next installment of Sites We Can’t Live Without features Eventful. Going to Chattanooga next week and need something to do on Saturday night? Or did you sit around last weekend because the Gamecocks weren’t playing? Eventful is a free online calendar on steroids. It features search, subscription, iCal syncing, and (natch) tags.

Like MyWikiMap, Eventful is user-driven. If you wants more events, you adds more events. Now get to it. Colaspot wants to crash your tailgate party.
