The following are sites where you can get other particular scripts that may match your needs. If you're paying for hosting service, your provider should have one for you. If you're getting free hosting service from your organization such as a university, you may try to install the script by yourself, but don't forget to ask the system administrator whether he or she allows you to have CGI Script.
