If your site is in any language that contains characters other than Latin, forget it. Most of the actions that can be taken after the quiz will not work. There is not much you can do about it. Problems will arise from anywhere.

But even if your site is based on Latin characters, I am sure that you will find the whole thing too un-friendly and ugly. It comes with 2 templates which they can be rated as bad and even worse. If you are not a really experienced PHP user and ready to dig through code to fix the simplest thing, don't bother.

I have also noticed some incompatibilities with certain Joomla templates causing more problems.

After sales service is poor to non-existent. After 48 hours of asking for help in their forum and via email, I was totally ignored so I had to launch the quiz with serious drawbacks and aesthetic errors.
