Official Google Docs Blog: Stop sharing spreadsheets, start collecting information

We're really excited to bring you forms! Create a form in a Google Docs spreadsheet and send it out to anyone with an email address. They won't need to sign in, and they can respond directly from the email message or from an automatically generated web page. Creating the form is easy: start with a spreadsheet to get the form, or start by creating the form and you'll get the spreadsheet automatically.
