If you need to poll a big group of people, Typeform offers an intuitive interface and a ton of options, all for free.
The de facto free choice for creating web forms and surveys has been Google Docs, but Typeform has a much nicer interface, and a few more options. The survey creator lets you drag and drop 20 different question types, each of which has a ton of options like requiring responses or adding multimedia. Once you're done, just share the link to your survey, and watch the results roll in on an easy-to-read analysis page.
Typeform is in open beta, and only lets you create three forms with 20 questions and 5,000 responses at first. Sharing a few words about it on a social network though will remove the restrictions.I just created a form for my ministry - you can view it HERE.
And let me just say, that I am incredibly impressed! The interface to build the form was super easy, the design and functionality is superb and the options to deliver the form, either through link, embed in website or pop-up, are fantastic.
This is going to be my new go-to form option!
