Bookface is the equivalent of a social calendar secretary. That's the only functionality I need from it.

I need a service with which to invite those of you on my Mastodon network to a party or convention, and manage the RSVP list. And to coordinate when my collaborators will meet to work on our projects and organizations. It needs to combine the day/time voting of Whenisgood.com with Meetup.com

I thought perhaps upcoming.org would do it, but no.

So I'm going to make it. #projectdovetail
