Sure, I'd be happy to continue scheduling people! I think it might also be useful to (eventually) simplify the job of scheduling by making it semi-automated. As we got closer to the cut-off date, I ended up asking each participant for precise time ranges when they would be available, to make sure we could fit as many in as possible before the cut-off, so there was quite a bit of back-and-forth. This would have been a bit simpler if we had a public calendar where you could book a block of time to participate. I'd be happy to implement something like this (a simple web app) mainly to make my life easier. It could also be reused for other ceremonies e.g. the alt_bn128 one you suggested. It would still need someone to be "coordinator" simply to ensure everything is running smoothly, and to occasionally override the calendar if there's something particularly important (e.g. yourself and Ryan with the Chernobyl nuclear waste). -- Jason Davies, https://powersoftau.plutomonkey.com/
