Quiz email and other features question

Hi there, I was wondering if this plugin allows for:

1) When a quiz is created, an email is automatically sent out to all users(members) on the site. The email preferably has a link to the survey and each member can only submit it once.
2) When a quiz is published and available. Is there a way to lock it so that admins CANNOT edit it until everyone has finished the quiz?

Thank you
