If you use the http://yoursite/user/register it will automatically send the person an email directing them to "activate" and a second with a link to the site. You can modify both those emails (check in standard/template/user/ for them)
Thanks, but it not the way I want. There is only 1 user for all with known password. He gets the email with the link manually, when he clicks on it, he is logged in an upload area.
