A Question About Registration Mails

Hi Guys,

I am trying to customise registration mail templates. And i realised something,

1- When an user register to a site, moderation activated, firstly user gets aprovals mail with username/email + pass
2- If admin aprove user aplication, user gets aproved mail with username/email and a login button (without pass)

I think we are going wrong way! why? Because user will need a pass after aplication aproved, so password should be in approved mail (cause pass generated randomly with Facebook registration) or both .

So i copied these codes below from aprovel mail template and paste them to aproved mail temlate, but i got pasword: (empty) in aproved mail, what i am missing ? Please look at screenshot attached

<table align="center" width="380" style="margin-top:-35px" border="0" cellspacing="0" cellpadding="0">

			<tr>

				<td style="color:#888;border-top: 1px solid #ebebeb;padding: 15px 20px; background-color:#f8f9fb;font-size:13px;text-align:center">

					<?php echo JText::_( 'COM_EASYSOCIAL_EMAILS_USERNAME' ); ?>: <?php echo $username;?>

				</td>

			</tr>

			<?php if( $this->config->get( 'registrations.email.password' ) ){ ?>

			<tr>

				<td style="color:#888;border-top: 1px solid #ebebeb;padding: 15px 20px; background-color:#f8f9fb;font-size:13px;text-align:center">

					<?php echo JText::_( 'COM_EASYSOCIAL_EMAILS_PASSWORD' ); ?>: <?php echo $password;?>

				</td>

			</tr>

			<?php } ?>
