          If you would like to require users to confirm their e-mail addresses by way of account activation, you can enable this behavior here. If this option is set to "None", users will be able to register and use this site without confirming their e-mail addresses. If this option is set to "User", users will automatically be sent e-mails upon registration with a link to activate their accounts. And lastly, if this option is set to "Admin", users' accounts will not be active until an administrator activates the account.<br /><br />

          You may also disable registration completely if needed.<br /><br />
