An event where supporters can take part in person or online, bidding, buying raffle tickets and donating in the same campaign as the people in the room.
No. With parallel participation, online supporters use your campaign independently, with no stream. Streaming adds atmosphere, but it needs a camera, a crew and reliable internet.
Have a stream failure plan ready, with a pre-written message for online supporters, so bidding and donations can carry on while you fix it.
