Auto Extract Email Adresses when visitors come to website

We would like a script written that will enable me to automatically obtain the email address stored on every website visitors computer, in their email programs folder or in the system registry. Ideally this would be done with no intervention on my part and all emails would be stored in a text file or emailed to an email that I specify. If this is not possible then I am in need of code that allows me to put a click box on my page where I user can just click on it and their email address is sent automatically. I have already seen jscripts that allow this to happen but it invokes the user's email program and actually sends an email only if they click send. At a minimum I need a one click subscription method for my ezine that doesn't rely on a popup only a clickable button or link on the page with no further intervention by the user. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
