Hi

I have set up website for a fantsy football game. It is part of my college project and i will be asked questions about the website. One aspect which i dont really understand is on my registration form.If a user is registering and the name that they are typing in begins with the same letter as a previously entered name, a list drops down with that previous entry. Is this just a history feature of the html code or is it something else. I would be very grateful if someone could give me an explanation about this as there is a good chance that i will be asked about this.

Thanks

Patrick
