Imagine your daughter studying abroad, your father travelling or somebody near not being near…
Wouldn’t you like to receive their alerts too ?
First step would be to select the people you would like to follow, or to accept followers request from others.
Second step will be your selected contacts to accept you follow them.
In case of emergency, when you receive an alert, automatically your selected contacts will receive the same alert stipulating clearly that it is an alert for you, and not them.
