hello i wrote something for conference organizers https://blog.frankel.ch/dos-donts-conference-organizers/ if you’re interested in reading it 🙂 (not specific to kotlin though)

Another note about reimbursement during non-covid times: Offering reimbursement would allow more diversity in speakers. Folks who otherwise would not be able to afford to travel to your conference, would now be able to be a speaker at your conference.
