When we get to 10:00 (Our scrum runs from 9:30 - 10:00 AM) he announces "It's 10:00, and this meeting is done." and hits the Send Button on the email.
I realize that this can be all done on a Wiki, or other mechanisms, but it's surprising how _reassuring_ it is to know that I have on my laptop/iPhone a detailed list of all the strategic/Commitments/P1s/Sprints/Tasks that the org is worried about today/this week. Also, it's a very efficient mechanisms for the person taking notes. Their job is complete before we leave the room at 10:01 AM.
And, additional bonus - when I have my Staff meeting on Mondays, at 11:00 AM, half of that meeting is simply going over the relevant parts of the email that was sent out at 10:00 AM.
