I've been a Joomla user for a number of years and have used a lot of extensions. BF Quiz Plus is a well-built extension. I have it running on 2.5.3. It installed easily. I had some issues with a few of the functions. I was getting error messages for the report and stats. Tim responded immediately to me and fixed the install for me. Seldom do I see such a great level of service. He truly stands behind his product. I was able to get my first quiz up and running after getting used to the program. There's some complexity with the program. It's not drop dead simple. There's a learning curve. With some tweaking my 20-question quiz was up and running. I found the menu item for the quiz has a lot of functionality that affects the presentation of the quiz. I'm very pleased with the component and would recommend its use. What makes the purchase worthwhile to me is the level of service Tim provides. Tim said he's working on an updated user guide which will be very helpful. It's an excellent extension and I'm glad I purchased it.
