This week I needed to create a simple survey. I could have just created a form but I wanted a better way of displaying the results. I opted for bfSurvey as there was a free version I could try and a commercial version with the features I needed. The free version is limited to 5 questions which is often all you need in a basic survey. Compared to other survey applications I have used, this one is pretty basic but it works well and is definitely worth a look if you want a survey on your Joomla site. There is a "Pro" version too.
