Google Docs Spreadsheet has got a new feature “forms!”, that lets you create a form to accept data. You can now create form* in a Google 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.
*When you go to the Share tab, there's a new option to "invite people to fill out a form". The form is very simple and can be customized by changing the order of entries, their labels and the type of answers. It's also a nice way to get feedback people who wouldn't normally collaborate on a spreadsheet.
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. You can create forms from spreadsheets or using this URL.
Once you create a form, responses are automatically added to your spreadsheet. You can even keep a closer eye on them by adding the Google Docs forms gadget to your iGoogle homepage, created by software engineers Valerie Blechar and Sarah Beth Eisinger (in her first month at Google!). It lists your recent active forms, with new responses highlighted. Add this gadget to your iGoogle page:
