I proposed an idea to speak at Midwest PHP in Minneapolis, so I travelled domestically to speak. The event gave me a free ticket, and I was not paid to speak. The event assisted with part of my travel and accommodation. My employer did not pay my travel expenses, and I was working while speaking at the event. My speaking slot was 50 minutes for this event, and I had a mostly good time. I'm a man who has been speaking for 7 years. This was a not for profit event. Also, The conference covered airfare and 2 of 3 hotel nights for a 2 day conference.
