Translation

In order to use the translation option, the line 380 in invite.module:

$items[] = array($invite->email, (($invite->expiry + (variable_get('invite_expiry', '30')* 24 * 60 * 60))< time()) ? "Expired" :($invite->timestamp ? t('Joined') : t('Pending')),$invite->timestamp ? "delete" : l(delete,'invite/delete/'.urlencode($invite->email)));

Should be:
$items[] = array($invite->email, (($invite->expiry + (variable_get('invite_expiry', '30')* 24 * 60 * 60))< time()) ? "Expired" :($invite->timestamp ? t('Joined') : t('Pending')),$invite->timestamp ? "delete" : l(t("delete"),'invite/delete/'.urlencode($invite->email)));
