When you sign in, check the "Remember me" checkbox, and then click the Sign In button. The sign-in process will remember your email address and password the next time you come to Network of Circles. Don't use this option if you are on a public computer, since the next person to use the computer might be able to sign into your personal account.

Once you sign in, you will stay signed in, and you won't have to do it again. But once again, if you are on a public computer, be sure to sign out when you leave.
