Write an Async Update That Replaces a Meeting

Act as an async communication coach. I want to replace a recurring [MEETING_TYPE] meeting with an async communication that achieves the same outcome. The meeting currently covers: [MEETING_CONTENT]. The attendees are [ATTENDEES] in [NUMBER_OF_TIMEZONES] time zones. Design an async update format: the structure of the written update, the response mechanism (where people reply, by when, with what), how to handle decisions that arise asynchronously, and the criteria for when to escalate back to a live meeting.
