Fill out a form once?

[nollieflip]

I am trying to figure out how to configure a form so that users only have to fill it out once...

What I have is a download page, before the user can download any files off the page they need to submit a form mail to me. The catch is I only want the user to have to fill out that form once.

Does anyone know of a method to do this? (cookies?)

If you are confused here is a sort of menu/tree that show's what I am trying to accomplish

first time visitor
download link > form page > download page

visitor who has registered
download link > download page

Thanks!!

Yes, you would probably give the registrant an id or ask him to choose and, and would store a cookie. So if they clear their cookies, they can use the id next time

Thanks, I think for the purposes of this site I would rather not generate ID's and passwords for each user that registers... Would there be a better way of just remembering if a user has seen a page and forwarding him/her on to the next one if they have?

If they delete temporary files and the form shows up again, I don't care about that.
