Ask each organizer in channel each month whether they are still active

We could write a script to run monthly. It could check who's in `#organizing-open`, and message each one with an "ephemeral message" (only visible to them) with two buttons:


(except it would be from a bot, and not me :) )

The idea would be to use it to update a google doc, which would have some other info, like the linkedin info or whatever. If someone said no, it would just mark their row in some way.

This would allow people to stay in the `#organizing-open` chat without feeling like they have to do anything, but it would mean we got to have a bit more understanding of who's an active organizer (which might be particularly helpful for new people :) )
