You told so much about your experience in conducting hackathons and how much important to make it great for participants.

I applied to your hackathon in Luma, got into the waiting list and did not received neither any response nor eny email. Will I be able to come and watch as guest or not. Should I come or not?

No feedback, no response, no contacting the potential hackathon participants. Does not seem like a good guest experience :)
