You get the ability to direct your messages to what you prefer. Say a friend added your e-mail to the group. By signing up, you can route the messages to your gtalk or sms or web instead.
Ok, that solves the signup problem.
So you still need to get the contact details. Not as hard as getting friends to sign up. What is the advantage of non group creators (non-admins) signing up then?
