Question Editing, points and

Hi, i've some questions to ask about VBQUIZ:
1- What's the file for template editing?
2- Is there a method for knowing who has completed quiz with lower time and higher points?
3- Is it possible open the quiz only for users who have a certain number of messages?

Thanks

Tagging @Dylan so he is aware of this question and kannon so he is aware of the response.

I'm sorry I didn't see this post for some reason kannon. Do you still need me to answer questions?
