I was sponsored to speak at Swiss Perl Workshop in Switzerland, so I travelled internationally 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 a student when I spoke at the event. It took me 7 days to prepare for my 25 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 1 year. This was a not for profit event.
