[brainstorming] how to make an event-specific announcement chat

off the top of my head, given our current infrastructure, if I wanted to start a "we're having a space cleaning party, here's a low-noise way you can stay up to date about what the details are and any updates or changes"

• create a new wiki page or whatever online doc ("public doc") that contains the original announcements and any further updates
• create an announcement only signal group "RC Cleaning Party [DATE]" with the public doc in the description (ideally with an expiration date for the chat in the title or description)
• post to 9 (or more) working group chats with the TLDR version of the announcement, a link to the public doc, and a link to the announcement only signal group
• any further announcements will be both added to the public doc, posted as a message to the announcement signal group, along with the link to the public doc
• once the event happens, post to the announcement group that
  

cons:

• initial announcement creates a lot of noise across the signal chats
• people have to join yet another group chat
• no backscroll for people who join after certain ideas or conclusions have been made (~LP)

pros:

• the public doc part of it addresses the fact that any newcomers to the signal group won't have access to any previous chat history
• the hygiene around chat management (an enforced expiration date and deletion protocol) lowers the psychic weight of joining yet another signal chat (at least form my perspective)
