Relying on a SurveyGizmo account and API, the SurveyGizmo plugin still seems rather interesting.
The SurveyGizmo plugin for WordPress gives you the best of both worlds. Use SurveyGizmo to build powerful, sophisticated and custom styled surveys, but stay in WordPress to monitor responses. The plugin also makes it easy to quickly edit, preview, or grab your publishing links.
It puts a survey tool inside the WordPress dashboard, allowing you to take stock in your users answers without ever leaving your admin console. I’d love to see some reviews on this plugins, so give it a test, and let me know how it goes.
