Organize your own events from events listed on popular websites. The Presdo Event Calendar Organizer lets you invite friends to events when you see an interesting event, activity, or place to go. A button is added anytime you see an event. Simply click it to create your very own invites to the event! The Organizer even works with Google Mail.
The add-on works with the following websites: Buzznet, Eventful, Evite, Facebook, Fandango, Google Mail, IMDB, Last.fm, Meetup.com, Moviefone, Movietickets.com, MySpace, Opentable, Ticketmaster, Upcoming.org, Yahoo Movies, Yelp, and Zvents.
The Presdo Event Calendar Organizer will notify you of upcoming events on your desktop (using Growl), and lets you keep track of all your events in one place.
