Suppose you searched for passwords for a site using password-login.com (search section is on the top of every page).
When you use a password and you worked, give a positive vote (green check).
If that does not work, give a negative vote (red circle with white line on it).
If the site you access has no user or password, you create an account and enter it into password-login.com - sure other users will thank you.
Thank you for using this service!
