I proposed an idea to give a workshop at MozFest in London, so I travelled internationally to speak. The event asked me to buy a ticket at full price, and I was not paid to speak. The event did not pay for my travel and accommodation. My employer did not pay my travel expenses, and I was unemployed when I spoke at the event. It took me 10 days to prepare for my 2 hours speaking slot, and I had a great time. I'm a man who has been speaking for 6 months. This was a not for profit event.
