Events your people are hosting

When someone in your Orbit hosts an event that's open to their people, you don't need an invitation to see it. It shows on the Your Orbit tab of Events, beside Yours, and on your Calendar as a quiet entry. A friend of a friend who opened an event to their network shows up the same way, marked Your network.

Answer Going or Maybe and it moves onto your own list, exactly as if you'd been invited. Not for me hides it and tells nobody: nobody invited you, so there's nothing to decline.

Home names the soonest of these at the top of Around you. And if you're one of the host's closest people, you may get a heads-up that they're hosting, sent once, a little while after they create it. Anyone they already invited doesn't get it, so you only hear once.
