How do I find people for Reboot Rally?

Hey there, I'm trying to organize a Reboot Rally but I'm not sure where to start when it comes to finding participants. Do you have any tips or strategies for reaching out to potential attendees? Are there any specific platforms or networks I should be focusing on? Additionally, how can I ensure that the people I reach out to are genuinely interested in the event and what it stands for? I'd love to hear your thoughts on this!
