I was invited to speak at mediaconvention (part of re:publica) in Berlin. This was a local event. The event gave me a free ticket, and I was paid 250 EUR to speak. The event did not pay for my travel and accommodation. My employer did not pay my travel expenses, and I was a student when I spoke at the event. It took me 2 days to prepare for my 50 minutes speaking slot, and I had a mostly good time. I'm a woman who has been speaking for 1 year. This was a not for profit event.
