NoGuest blocks all guest screen names logged into America Online. Why would you want to do this? If you have parental controls set for your kid's screen names on AOL, they could use a friend's screen name to get around these settings and have full access online. NoGuest will watch for any guest logins and immediately shut down America Online. It will also keep a log of all guest screen names attempted to be used. This is a must for any parent with kids who use America Online! Register your copy today.
