Redzone was started by one of Redline's founders while involved as an executive member of an amateur sports organization. This organization realized how vital it was to have a presence on the Internet for efficiently communicating with its membership and for promoting the league.
Many leagues don't have the resources to create a professional looking website or the ones that do, simply don't have the time. Sports leagues are run primarily by volunteers, so time spent on league affairs is at a premium. Redzone was designed to maximize their productivity.
