Install the bot. Pick where Family Drill runs.
The organizer verifies once and adds family emails in the bot. Relatives do not set anything up. They receive occasional surprise practice messages.
Either way, the flow is the same: install bot → verify organizer → add family emails → send surprise drills → review what landed.
