Create polls, surveys and quizzes and get ratings/feedback on content from users. "All languages supported." The free version has fewer options.
At the paid levels there are design options such as customized branding and CSS control; collection options include 10k-50k (depending on purchased plan) of monthly participants and password restriction; and it is in the reporting methods that this program has the most depth: real-time results, charts, the ability to export responses and reports as Excel, PDF, Google Docs, CSV or XML, filtering options, text analysis, tagging, email notifications of new responses, and priority customer service. Also, you can add images, videos, and content from YouTube, Flickr, and Google Maps.
This works with Wordpress.
This was previously Surveydaddy and has been upgraded to Polldaddy.
