Great beach report. The ship will be harder, but it’ll get better.
The Shout does not go through the relay or anyway but directly from the sender to the receivers within range of that single hop between them.
Group messages do forward through the relay, as do all addressed messages. That’s one basic difference between the two. In Shout, it’s like a CB or party line, everyone in range hears it.
With 1to1 and Group Private Messages, it only goes between you and your specified recipients.
