But the Centre for IT Services will not accept any other scripts on our Web server. We are accountable to all NTU users when the server fails. People will ask to put something up, but they may not tell us when they no longer need the program. We have thousands of users using our server, so even if only one percent of the users have a special program on the server, the tracking work will be quite substantial. Set up your own server if you know how and have the equipment to do so.
Some schools have their own servers.
You are free to call any other free services from other Websites on your Web page. E.g. some people use counter programs from overseas servers, or other free guestbook services.
