I think myLot won't show the members' private information for public
such as email address to protect the members from any spam attack.
so far you would have to send private message to them and request the email address personally.
I think so. There is no easy way of getting the email address of your friends than by requesting each of them. It may take you some time but if you're really that interested, you might as well be patient. Good day to you!
