How can I get Google Docs to register IDs of people taking a survey generated from by the form? I have a database of users and I'd like them to take a survey and also have the form link with their id so I know who of my users completed the form.
Is it also possible to style a Google Docs form or do I have to stick with one of the few styles provided by Google?
Is all of this possible with Google Docs? If not, I may look into Survey Monkey if it provides these features.
