As a member of the South Florida WordPress Meetup Group, make sure you are on the WordCamp Miami 2013 mailing list. It's one of the best ways to be first to know important updates, such as official dates, ticket discounts, and contests.
We are making the first of several special announcements soon, so if you missed our notice a few days back and haven't signed up yet - you might want to start now.
Also, if you have some input on what workshops and advanced sessions you would like to see at our 2-day WordCamp this year, feel free to add your $0.02 here:
