The title of this review says it all. I can't believe this extension was only $5. We are running it on the employee portal of our company website which is running J3.23. We use it as a training tool for our new employees. I also plan to use it for existing employees. The reporting feature will allow me to gauge where our staff is at in terms of knowing their jobs and our products and that will allow me to tailor my refresher training courses to what areas they need help in the most. The Extension installed easily. I did have one hiccup but I think it may have been my fault. In any case, they were quick to fix the problem. I didn't even have to do anything beyond open a support ticket. I opened a ticket, and went home. When I came to work the next day, I had a message stating that the problem had been fixed. How could you ask for anything more than that? If you need am inexpensive way to add either feedback or a quiz function to your site, you can't go wrong with this extension. Besides, it's only a $5 donation, so there's basically no risk involved to try it. I have a feeling we are going to be using this for many years to come. Oh one more thing, whats nice is how fast and easy it is to create quizzes. I had a 12 question multiple choice quiz up and running, (Accessible only to our employees) in less than 5 minutes. Hopefully the creator of this code doesn't take this to heart, but I'd have paid a lot more for this extension had I known how well it was going to work and be supported. Keep up the great work!
