I think I am going to use Google spreadsheets and an embedded form. I see that it is possible to pre-populate the fields with URL parameters. So I think I just need a way to redirect with the correct data from a database when a user goes to their Personalized URL.
I have no idea how to do the second part. Or if it is even the best way to do it.
How do I set up Personalized URLS?
How do I redirect from those URLS to the spreadsheets?
Is this even the best method for pre-filled forms?
