                    Hi,
In my website, if someone registers new using create user wizard, I don't want him to go straight away to his home page.
I want to SEND HIM A LINK to HIS EMAIL ID and i want him to LOGIN
THROUGH THE LINK WHICH I SEND TO HIM (when he logs in first time) via
email,
If he has not activated his account by loging to the site through the
link which I have send to him, his account should not be active, if he
attempts to login 
through his login page. How can I implement this?
Thanks,
