To join, open the invitation or enter the pool code, then verify your own mobile number. If you are not listed yet, request to join; a manager approves access. Choose to join with WhatsApp updates or without them. Saving the Key Carpool contact does not grant access to a private pool.","whatsapp":"Ask the assistant who’s driving, check your schedule, request a ride change, and send pickup updates from your Key Carpool WhatsApp chat. Choose WhatsApp updates when you create or join a pool to receive reminders. Initial setup and some detailed changes, including reviewing imported drafts, use the website.","reminders":"Choose WhatsApp updates when you create or join a pool. Later, use Pool → Edit my contacts to change your ride alerts and reminder preferences. Manager alerts also have controls in Manage. Reply STOP on WhatsApp to stop WhatsApp messages.
