📖What it is

Sends and receives all WhatsApp messages and attachments for the team.

This is the team's WhatsApp post office: it carries messages, photos, and files in and out over WhatsApp. It just moves the mail and doesn't decide what to say. Carol and about fifteen helpers depend on it to talk to people.
