[Tock Devel] Call for Tock meeting agenda items

Please reply with agenda items and +1s for today's meeting. Hudson is away today, so I'll be leading, hence the later than usual request for agenda items. Luckily I think there are plenty. I suggest at least: - Brad's suggestion for a new documentation working group (there is already approval for this, but we can maybe discuss whether/how to support this kind of process more generally. could be very brief)
