Help:Email confirmation

Wikipedia requires that users confirm their email addresses before they can use email features such as emailing users, receiving email notifications, and the ability to reset your password. This helps to prevent problems with bad addresses or spam. You only need to confirm email addresses to use the email system; you can log in and edit pages without confirming your address. You are not even required to enter an email address to register; it is optional. (However, administrators are expected to have a confirmed email address.)
