Seems reasonable. The host is effectively the moderator, so they decide who receives an invite. The host can also mute or kick unwelcome visitors from the Zoom meet-up. This way they can keep the flow of the agreed upon conversation on track without any painful friction or bickering. The host would just need to share the Zoom meet-up link via private message as opposed to making the link public, so it effectively becomes invite only. Yak could pick a date and time that works for everyone, announce it on this thread, and then send out PM invites. BAM!
