update: The overseer and I have agreed on a final extension until Wednesday. I've been keeping in touch with participants yet to complete their entry to avoid uncertainty, and this should be enough time for everyone to complete their entries, while Wednesday also allows me to prepare for a smoother and more efficient setup process, particularly since I have time to work on it that day.
If you haven't already, check out the second post on this thread, which has information on the host city, the venue, and the show hosts!
