I was unaware that I could join the powers of tau after March 20th. I was told on the zcash community chat that they were no longer accepting new participants. I would love to help out here if someone could tell me how. Regarding a semi-automated calendar, something like Doodle ( https://doodle.com/) could work. The platform does not have to be trusted, so any free online group scheduling service would work.
