I proposed an idea to speak at Zendcon in Las Vegas, so I travelled domestically to speak. The event gave me a free ticket, and I was not paid to speak. My travel and accommodation was fully covered by the event. My employer did not pay my travel expenses, and I was working while speaking at the event. My speaking slot was 60 minutes for this event, and I had a great time. I'm a person who has been speaking for 4 years. This was a for profit event.
