We don't currently offer a survey tool directly, but we do have the ability to create custom surveys. However, there are low-cost and very effective services that work perfectly well with our software. One of the most popular is Survey Monkey, http://help.surveymonkey.com.
Survey Monkey does require an account. Instructions for creating the widget-based poll are here: http://help.surveymonkey.com/app/answers/detail/a_id/161/kw/iFrame.
Once you've created your poll, just paste the widget directly into our site using Advanced mode.
