One of the coolest things about google docs is that it has the ability to capture data inside a form and store them inside a spreadsheet that is updated dynamically whenever a new person fills out the form. Unfortunately the styles google gives are a bit limiting and the branding that they put at the end of the form is not always desirable.
Strip out the branded code and build a custom form that talks with the google database. Below you can see the code I used for one of my projects. Line 2 and 3 are very key because this is where you tell the information to go and the redirection after they fill out the form.
