Hello, I would like to buy this combonent in behalf of my client and before I do that I want to ask for some special features.

1. Is there any ability for the user who wants to run the quiz, to see the questions mixed up so everytime he sees the questions in another order?
2. Can we put in the quiz 500 hundred or maybe more questions? Is there a limit?
3. Is there the ability when the user finishes the quiz, the combonent to send an email with the results to the administrator and to the user?
4. Can the administrator do a search query with the name of every user and see if he has runned the quiz to the back end of the combonent?

If something from the above questions the combonent doesnt support, how much it costs to put it in custom development?
