Just an FYI: I received an email cancelling my Trade Day tickets. While I'm presenting at Trade Day, we don't get a trade day badge. An error in the ticketing/badge software was allowing anyone to register for Trade Day events so when their IT fixed the error, it refunded those events for everyone without a Trade Day badge.
I called customer service and wanted to pass on their answer: Presenters at Trade Day can still participate in Trade Day events.
I hope there is some type of "Presenter/Speaker" ribbon for us. I'm a VIP at our local comic con and have had to argue with security several times over my status (funny story there for another time).
