Examples of submission forms used in NTU include the feedback pages you see throughout the NTU pages, like the NTU homepage, and the Centre for IT Services feedback forms. Besides gathering responses from visitors, the interactive element also allows the creator of the form to use it as a simple kind of online application form. The Centre for IT Services' Helpdesk has an online fault reporting form. This is another use for this kind of simple CGI-based forms.
The forms you fill in StaffLink and StudentLink applications are generally NOT the kind of forms we are referring to here. Those are more complex as they have to interact with a backend database. They are developed by professionals with programming skills, and are too complicated for the layman to learn.
